  1. Acoustic Components in the Medical Industry 

    April 21, 2020 8:19 pm Leave a Comment

    Patients and medical practitioners both benefit from quieter environments, but hospitals and laboratories often have high levels of ambient noise. Even clinics, offices of private practitioners, and homes of recuperating or long-term patients still have noises that may cause distraction or anxiety.

    Acoustic-Components-in-the-Medical-Industry

    Noise absorbers and sound dampening materials are important throughout the medical industry as patients and medical professionals seek to reduce noise levels. OEMs are often asked to reduce noise levels on equipment such as: 

    • Diagnostic and testing equipment 
    • Home-use medical devices 
    • Hospital-based care equipment 
    • Patient care equipment

    reduce noise levels medical equipment

    Medical Environments That Require Sound Absorption 

    Good medical acoustic design involves balancing competing interests. Enclosed devices can have more sound-muffling technology, but visible controls facilitate easier use. Sound-absorbing outer shells might make equipment maintenance harder even as they quiet the noise level. Striking the right balance between these factors can dramatically increase the comfort and usability of medical equipment. 

    Medical Environments Require Sound Absorption

    Some of the specific benefits of good acoustical design include: 

    Patient Satisfaction 

    Noisy settings can be stressful and displeasing. This negative impression can impact a patient’s decision to choose your facility and their perceived quality of care. 

    Better Employee Focus and Productivity  

    Loud, unusually low-pitched or high-pitched, and/or repetitive noises (often referred to as tones) can distract employees. Adverse acoustic conditions can also impede clear communication or cause doctors, nurses, and medical staff additional stress in what may already be a stressful work environment.  

    Removing or minimizing ambient noise and tonality in equipment can improve employee performance by reducing the risk of error, improving communication between staff and patients, and improving employee satisfaction with their workplace. It may also reduce HIPAA violations and better protect patient privacy because staff can speak more quietly.  

    Improved Health for Everyone in Contact with the Acoustical Environment 

    Adverse acoustical conditions have negative physiological ramifications. Reducing exposure to loud, grating, or repetitive sounds can help patients heal and can be a crucial part of promoting a healing environment. Quieter work conditions also reduce stress, headaches, and anxiety. 

    Solutions Design for Acoustics in Healthcare Environments 

    Sound Design for Acoustics in Healthcare Environments

    Choosing the right acoustical components for a medical application is essential. Sound technicians can add acoustic insulation behind exterior covers to dampen internal vibrations and noise pollution caused by medical equipment. While the external covers protect the internal machinery from contamination, air exposure, and damage, the covers also provide the right surface area to install acoustical absorbers. Large equipment such as blood analyzers, magnetic resonance imaging (MRI) chambers, and oxygen concentrators can all benefit from acoustic insulation without suffering any loss of performance. 

    The search for high-quality acoustical components is not the only important factor to take into consideration, but finding the correct manufacturers is vital as well. You do not just need a solution that absorbs, blocks, and isolates sound, but you need solutions designed and developed by a manufacturer to match every specification. The quality of these solutions is only as superior as its manufacturer.

    patient specific health benefits

    This is especially important for medical equipment that continuously runs near patients. Patients staying in the hospital overnight or for long periods of treatment need to have calm, quiet conditions. Reducing ambient noise levels by insulating the nearby operating machinery creates patient-specific health benefits such as: 

    • Better sleep 
    • Improved general safety 
    • Superior quality of communication 
    • Lowered blood pressure 
    • Reduced stress and anxiety 
    • Less demands for pain medication  

    Does Your Equipment Require Noise Reduction? 

    Most medical environments can benefit from noise reduction technology. These locations become safer and more hospitable for both patients and medical professionals when there is less noise and vibration.  

    Does Your Equipment Requite Noise Reduction

    At Technicon Acoustics, we’re here to help with all of your sound control needs. We offer the following healthcare acoustic control products: 

    Acoustic Absorbers 

    Once sound leaves a device, it becomes airborne. Our acoustic absorbers muffle this airborne noise by absorbing the soundwaves. We produce porous acoustic foams, also known as sound-proof or sound-absorbing foam. This foam comes in a variety of thicknesses and facings.  

    Our team can customize acoustic absorbing layers to target the specific frequencies of the noise pollution in your application. By adding this material to surfaces that can reflect sound, you can control the total ambient noise within a space. 

    Acoustic Barriers 

    While acoustic absorbers control noise within a given space, acoustic barriers contain the sound so it doesn’t spread in the first place. We’ve carefully designed our barriers to stop the transmission of soundwaves. By using acoustic de–couplers—which interrupt the transfer of the sound through media—and acoustic absorbers, you can control sound in and out of specific areas. We can also design our barriers with composite materials that perform all of these functions simultaneously.

  3. Acoustic Solutions to Portable and Standby Power Generators

    January 30, 2020 8:31 pm Leave a Comment

    A dangerous, yet easily overlooked problem in the power generation industry is the noise produced by standby and portable generators and turbines. This type of equipment can produce excessive amounts of noise and heat, eventually causing damage to the surrounding area, reducing the lifespan of the equipment, and creating an unsafe working environment. Acoustic enclosures offer an ideal solution to counteract these problems, along with improving customer acceptance and marketability.

    Fluid, Air and Pump Treatment Guide

    Equipment That Requires Sound Absorption

    The severity of noise pollution created by generators can vary depending on a number of factors. Motor size, the type of exhaust system, and the style of radiator fan installed can all impact the level of sound put out by a generator. Standby generators can produce noise up to 80  decibels or above, causing damage to equipment over time and posing potential health and safety risks for operators.

    While the intensity of sound can vary depending on the generator, the causes of the sound are generally the same on most power generation equipment. These sources include:

    • Engine noise
    • Engine exhaust
    • Turbulent airflow caused by cooling fans
    • Alternator noise

    Sound may be dampened considerably on power generation equipment by creating a weighted barrier to line the sheet metal enclosure of the generator. A decoupled weighted barrier may also be used for generator noise reduction, which involves the addition of decoupling foam to the barrier before installation.

    To ensure that power generation equipment continues working safely and effectively, it is important to provide several openings in a generator sound enclosure for heat and exhaust to be released. These openings also enable air flow to the machine. If heat isn’t properly released, it will eventually damage equipment.

    While these openings are vital for the functionality of your equipment, they reduce the efficacy of the barriers by allowing some of the sound waves to escape. To absorb sound that can’t be controlled with sound dampening liners, operators can incorporate acoustic absorbers as a lining for louvers or to create a tortuous path for airflow to absorb the noise before it escapes.

    Solutions for Portable and Standby Generators

    Acoustic control systems for portable or standby generators come in a variety of different types of material. They are built out of composite layers of foam, vinyl, and fiber and work by blocking, deflecting, or dampening the sound waves being created by the generator. This generator soundproofing material protects the workspace and ensures the longevity of equipment. These treatments are straightforward and easy to install. Typically, they are flexible and come with an adhesive that simply requires sticking them in the right place.

  4. The Importance of Acoustic Enclosure Treatments

    December 9, 2019 7:34 pm Leave a Comment

    Loud noises are not just distracting or uncomfortable for workers—they pose serious safety risks that lead to hearing loss. Reducing noise with acoustic enclosure treatments is an important element in creating a healthy work environment and facilitating employee productivity. These enclosures reliably reduce, minimize, or eliminate noise from specific sources in countless industrial environments.

    Benefits of Acoustic Enclosures for Noise Reduction

    Industrial machinery often exceeds allowable noise levels, but acoustic enclosures used in industrial environments facilitate noise reduction in compliance with federal, state, and local statutory limits. Noise enclosure treatments provide a number of benefits, including:

    • Measurable noise reduction, from 15dB(A) to 50dB(A)
    • Noise reduction for air inlet drive on combustion engines
    • Acoustic level reduction of combustion engine exhaust removal
    • Availability for indoor or outdoor applications

    Applications for Acoustic Enclosures

    Acoustic enclosures are present in a variety of facilities across a broad range of industries, applying noise reduction or elimination solutions to common noise pollution issues. Some examples include:

    Mobile electric power generator for emergency situations.

    Outdoor Generator Enclosures

    Outdoor generator enclosures reduce damaging frequencies from continuous engine noise. Though many portable generators integrate adequate levels of sound reduction, most industrial generators produce noise levels well in excess of OSHA’s permissible exposure limit (PEL). OSHA currently allows 90dB over a period of eight hours and only two hours of exposure to 100dB.

    Transformer Enclosures

    While transformers may not generate loud or intense noise, they do produce noise at a continuously damaging frequency. Transformer enclosures minimize the continuous humming and high-frequency noises commonly associated with this equipment.

  5. Micro Perf Myths

    November 26, 2019 6:06 pm Leave a Comment

    Controlling how and when sounds are absorbed is pivotal for equipment and machinery. Acoustic designers use a combination of tactics and materials to control sound absorption and direction. One method manufacturers use is adding layers of composite materials, foams, and films to create panels with different rates of absorption.

    Micro perf, or micro perforation, is a film with tiny holes. Manufacturers apply this perforated film to acoustic foams to help absorb noise. Ideally, this addition should make the acoustic foams and composites absorb sounds at lower Hertz levels without adding mass or weight to the foam. However, an internal study found this was not the case, as micro perforated materials that were tested alongside unperforated materials provided minimal distinctions in sound absorption.

    What Is the Proposed Advantage?

    Acoustic designers routinely look for ways to smooth out sounds without bulking up acoustic foams. Micro perf’s intended job is to help tune lower frequencies without impacting high-end frequency absorption. At Technicon we sought to determine if the perforated films were able to tune, or if they simply reduced the structural integrity of the film.

    What Is the Result?

    Tests of normal incidence absorption comparing unperforated films with micro perf materials indicated little to no signs of effectiveness. Perforated material did not change absorption across the frequency spectrum. While the tests indicated some marginal changes, the changes would not alter the sound experience. Listeners would not be able to perceive audible differences.

    During tests with random incidence absorption compared to micro perfs, testers found some material effects. Microperf created smoother sound absorption effects. But the cost of this modification was an overall higher frequency of sound. Unperforated material in the same random incidence environment led to similar results.

    Another limitation of micro perf is its porosity. Covering acoustic foam with nonporous films — with no perforations —has several benefits, such as preventing oils and moisture from contaminating the foam. But the holes make micro perf porous.

    In fact, the tests seem to indicate, micro perf just creates an additional expense with no added value, since micro perf is more expensive than non-perforated alternatives. The holes also allow substances like water, oil, and grease to damage the material. Perforations can also shorten the lifespan of acoustic foams by allowing UV radiation to degrade the material.

    Contact Technicon Acoustics for More Sound Science Help

    There’s no short cut to fixing absorption peaks and smoothing out sound. Instead, professionals need to be able to tune acoustic absorbers and find the right ratios between the foam’s composite layers.

  6. Absorbers vs Barriers

    October 25, 2018 5:31 pm Leave a Comment

    When you’re not really sure what solution you’re looking for you usually search for “soundproofing”. We receive calls that sound like “how do you make this oxygen air compressor quiet?” Or Is there a way to soundproof my office?

    People are convinced that soundproofing foam, sound absorbing foam or soundproofing panels are the “cure all”. Well, doesn’t foam stop sound?  No. Foam doesn’t “stop” sound. It absorbs echo. This is a common misconception that follows confusion when OEM’s and everyday people are looking for sound solutions for their next project.  Let us help you understand the difference and which one is best for your next project.

    What is an Absorber?

    Technicon Acoustics Foam for Sound Absorption

     

    First, let’s determine what an Absorber does. Sound absorbers are porous materials used to line hard sound-reflective surfaces to reduce airborne noise. Airborne noise is a sound that is transmitted through the air, typically generated by

     

     

    • Speech
    • Television and Radio
    • Animal Sounds
    • Transport

    In construction, you typically find structure-borne noise which is transmitted through a solid structure, such as steel, wood, concrete stone etc. Once the sound strikes the material, the sound energy is dissipated as heat. Typical absorbers used are acoustical foams and fibers. At Technicon Acoustics we produce absorbers that are acoustical foams and fibers for both functional and aesthetic purposes with a wide variety of foam or non-woven absorbing materials. Common examples of sound absorbers are open cell foam and polyester fibers. To determine the amount of material necessary to reduce the noise, our engineering team uses our Acoustics Lab to ensure there are no gaps, cracks or leaks to allow sound to escape from the enclosure.

    Common Uses of Sound Absorbers

    • Machine enclosures

    • Generator, air compressor, & water pump enclosures

    • Engine compartments

    • Truck & heavy equipment cabs

    • Home appliances

    • Medical equipment

    Click here for the technical

     specification for an Absorber.

    What is a Barrier?

    Barrier Composite

    Barriers (soundwall, noise wall) are slightly different than absorbers because they are used to block noise transmitting from one location to another. A Sound Barrier is a Mass Loaded Vinyl (MLV) used to reduce the amount of airborne sound transmitting through a wall, 

     

    floors, ceilings etc.

    While Barriers are heavy as lead, they usually aren’t that thick. This allows the MLV to improve Sound Transmission Loss without taking up space; like at a Construction Site. Barriers can be wrapped or be used with other material like our Thermal Solution Product Tech Shield.

    *Keep in mind, that noise can be absorbed by sound absorbers or blocked by a barrier. We can also reduce structure-borne noise that causes vibrations using our Damping Material. *

    Common Uses for Sound Barriers

    • Machine enclosures

    • Engine compartments

    • Firewalls

    • Bulkheads

    • Cab floors

    • Pipe Wrap
