What Does an Acoustic Consultant Do?

Acoustical Consulting is an engineering discipline that studies the science of sound and vibration. Often the need for an acoustician arises when excessive noise or mechanical vibration in space affects the comfort of the building occupants. In these cases, an acoustical consultant can measure the STC (Sound Transmission Class) between walls or the IIC (Impact Isolation Class) between floors and make recommendations to reduce unwanted noise in line with ASTM regulated standards.

But acoustic engineering is more than just noise control. Acoustic consultants are often brought in during the design phase of an architectural project to recommend structural assemblies or finish components that will reduce excessive noise and increase the intelligibility of the human voice, music, or other desirable sounds. Acoustic Consultants consider the volume, geometry, interior finish, and function of a space, then recommend systems that diffuse, reflect, and absorb sound to achieve an environment’s proper acoustical response.

Acoustic consultants also specify positive types of sound design strategies. Sound reinforcement systems, ranging from stadium and arena speaker systems to paging systems, assistive listening systems, and conference room microphones and telecommunications systems, all involve the physics of good sound design and acoustics.
