Reducing noise and vibrations

Acoustic comfort refers to being comfortable with the acoustic conditions in a given environment. On a vessel, sound vibrations – particularly from the engine – can create a number of issues. They may make it uncomfortable for personnel or passengers working and living on a vessel and can be detrimental to concentration, communication, rest and health. At the same time, vibrations can also cause structural damage. In this context, any noise reduction will significantly improve their experience, while ensuring you comply with noise and vibration transmissions under the ISO standard 6954. 

IMO-certified sound insulation, acoustic glazing, ceilings and walls all help maximise acoustic comfort and tackle challenges related to structural, vibrational, mechanical and ambient noise – whether in cruise ships, yachts or naval vessels. What’s more, sound attenuation solutions can also be combined with passive fire protection and thermal insulation to simultaneously increase your vessel’s fire, thermal and acoustic performance. 

Choosing your sound insulation boards

The main property to look for in your sound insulation board is dynamic stiffness. The lower the dynamic stiffness, the better the sound-reducing effect. However, if the insulation boards are too soft or thick, they may not be able to support the floor or provide the required point load capacity. 

Optiong for soundproof flooring

There are many sources of noise on board (engine room, vibrations, life on board, HVAC, etc.). Acoustic insulation flooring absorbs sound and considerably reduces noise and vibration impact. Ideal for special room geometries, Weber Marine dB Floor is designed to provide high sound insulation performance for any kind of ship or offshore installations and is effective against airborne, impact and structure-borne sound. 

Understanding acoustic glazing

To achieve the desired noise reduction, glass needs to be laminated or build up into a double-glazed unit (DGU). STADIP SILENCE acoustic laminated glass contains a special film interlayer that contributes to reduce sound transmission by suppressing sound waves intrusion around the critical frequency of the glass. It can be applied in single- or double-glazed unit (DGU) for glass facades, windows and internal partitions. In a DGU, STADIP SILENCE reaches an airborne sound insulation level of up to 54dB.

Why choose an acoustic ceiling?

A wall-to-wall acoustic ceiling, like those by Ecophon or Clipso, is often the easiest way to get a large sound-absorbing surface area to reduce sound strength, shorten reverberation times, and increase speech clarity and overall hearing comfort. However, for an optimal sound environment, you may well need different kinds of sound absorbers placed strategically, such as wall-mounted panels. For example, Clipso’s SO® ACOUSTIC ceiling and wall coverings offer high-end visual and acoustic solutions for any interior space within your vessel. CLIPSO® 495 D and 705 A acoustic coverings are highly micro-perforated for a high level of acoustic performance.

Beyond acoustic comfort

As well as offering high levels of sound attenuation, our solutions provide additional benefits to make your vessel more efficient and the experience on board safer and more enjoyable. For example, many of our insulation and flooring products are also fire resistant to contribute to an effective passive fire protection strategy. Your glazing can reduce noise levels while also creating visual interest and appealing aesthetics.
