New England Foam fabricates custom acoustical foam products for the following sound control applications:

• Control rooms
• Project studios
• Radio & television studios (broadcasting)
• Live rooms
• Houses of worship
• Stages & live performances
• Home Theatres
• Vocal booths

The following acoustical foam products are custom fabricated by New England Foam upon request:

• Absorption
• Diffusion
• Transmission control

Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations.

Yes, good sound can be described as sonic transmissions that were intended on being heard, or the original sound waves without any reverberation. 

Bad sound, on the other hand, can be thought of as unclear or “muddy.” This is due to the interference and multiplication of the original waves as they reverberate (echo) off of near-by surfaces.

This pattern of phase interference and multiplication is referred to as the “mud,” which is the culprit for most complaints regarding home theatre and recording environments.

Acoustical foam products fabricated by New England Foam greatly reduce unwanted "mud" and increase the listener’s ability to discern the intended frequencies.

The proper placement of the following methods of acoustical foam products will greatly reduce unwanted interference patterns:

• Absorption
• Diffusion
• Transmission control

Absorption, with regards to acoustics, refers to the property of a material; in this case, acoustical foam products, to alter (absorb) the sonic energy of a sound wave.

New England Foam fabricates acoustical foam products that effectively attenuate these sound waves by shifting, or absorbing, the acoustic energy into another form of energy (heat). 

Diffusion, with regards to sound control, refers to the distribution by which acoustic energy is spread (diffused) throughout a listening environment.

A sound space that is 100% diffusive has acoustic properties that are evenly spread throughout each listening position.

A sound space that is non-diffusive has wild, but ordered, reverberation that varies throughout each listening position. Essentially, all sound spaces are non-diffusive.

Diffusive acoustical foam treatments keep acoustical energy from grouping together.

This helps to remove “hot spots” or “nulls” and provides a “natural” sense of openness to the listening environment, making it easier to hear “into” the mix.

Diffusive acoustical foam product treatments destroy standing waves and trembling reverberation without removing the original acoustic energy from the listening environment or greatly changing the frequency of the original sound waves. 

Since diffusion can make small sound spaces seem larger, it may be ideal to add diffusive acoustical foam treatments, especially if your goal is too increase the amount of “natural” reverberation within a listening environment.

New England Foam fabricates custom acoustical foam products that effectively spread out, or diffuse, acoustical energy resulting in an ideal listening environment.
