Acoustic panels are sound absorbing panels placed on walls or ceilings to control and reduce noise, eliminate slap echo and control comb filtering in a room. The objective is to enhance the properties of sound by improving sound quality with sound absorbing panels. Often used to treat recording studio acoustics, church acoustics, home theater acoustics, restaurant acoustics, and listening rooms, the purpose of acoustic panels is to reduce, but not entirely eliminate, resonance within the room.
Get sound and noise insulation with these products. For walls, ceilings, doors, pumps, compressors, cars, and much more. You can also read our help topic noise insulation to the outside. When it comes to noise insulation between rooms, there are no or very few additional benefits to using convoluted or pyramid foam materials. You will need heavy foam materials which are as thick as possible for this purpose in order to be able to effectively insulate noise. The lower the frequencies and the louder the sound source, the thicker the foam material should be.
Acoustic glass is specialist glass that considerably reduces noise levels. All glass has some acoustic ability in terms of blocking outside noise – a 4mm single pane of glass has a sound reduction level of approximately 25 decimals (25db) and for a 4mm IGU with two panes of glass) this increases to around 28db. Sound levels may be reduced further in a number of ways including simply increasing the thickness of the glass being used or increasing the number of panes / distance between them within an IGU. However, the most effective way of increasing sound reduction is to use a bonded layer between two panes of glass – the bonded interlayer absorbs sound energy and prevents sound vibrations from travelling through the glass. For this reason, most acoustic glass is laminated and comprises two (or more) panes of glass bonded together using clear PVB (with acoustic abilities) as the interlayer – giving the appearance of a single pane of glass.
Room isolation designs are only as good as their weakest link, and residential doors present several challenges that can be met with AK’ line of wood acoustical doors. First, the door itself, if not well-constructed, will transmit sound energy from one room to another. Second, air gaps around the perimeter of the door, if not sealed, are easy pathways for sound to transfer to adjacent spaces. Additionally, most sound-rated doors are made of metal and are not attractive in residential environments.
AK offers custom-manufactured STC-49 and STC-35 sound-rated acoustical doors which have been specifically designed for residential environments and offer a wide variety of standard and custom wood finishes, sizes, and acoustical seals.
