We work closely with builders of production pleasure boats, custom yachts, and military craft to maximize comfort for personnel and passengers.
Our noise absorbing and damping solutions have been designed and manufactured to stand up to the most rugged open water environments.
Engine Room Treatments
In many cases the engine room is the original source for most of the noise problems generated in the marine envrionment. Therefore, there are a myriad of treatment methods employed to minimize the negative impact that this unwanted sound and vibration can have on your customers comfort. Technicon can assist you at this design phase in order to ensure that appropiate acoustical design elements are considered prior to any construction. This is often the most economical way to avoid have a noise problem.
Generator Set Treatments
Generator sets have many of the same sound sound features as the main engine and should be analyzed for treatment in much the same way. Even if the generator set is already located within treated engine rooms, it may be necessary to further treat the genset. Placing the genset in its own enclosure isolated from the hull structure and lined with the appropiate acoustical absorber or absorber/barrier composite is recommended.
Hull Structure Treatments
In many cases, despite exceptional work done to minimize engine room noise impact on the hull structure, the hull itselft by the virtue of its contact with the external environment can be a major source of noise problems. Secondary engine or shaft vibration, propeller caviation or even fluid dynamics can set up resonate modes in the hull that cause the entire boat to act as a giant surrounding sounding board or drum. The proper vibration damping materials applied strategically to the hull or deck can effectively dampen the resonate frequencies of the hull and minimize the noise problem and significantly improve passenger comfort.
Floor Underlayment Barriers
Noise transmitting from engine or generator rooms can be a significant noise source on boats. The addition of floor underlayment, made of closed cell foam with a vinyl acoustic barrier, is a simple but effective solution to managing sound levels inside the cabin. Floor underlayment is designed to reduce the amount of sound transmitted through materials, which dampens noise and/or blocks it from entering the cabin. Our acoustic floor underlayments are available in a variety of sizes and can be custom cut to fit the floor.
