Interior Finishes - Acoustics & Interior Finishes - Light Gauge Steel Framing

Acoustical and noise control concerns exist in almost every modern building

Most commonplace acoustical issues are resolved using a consultant's assistance?

An acoustical consultant is usually required for the design of a concert hall or to solve a complicated noise problem.

Most sound is non-complex, generally consisting of continum of frequencies.

Sound is the ear’s response to pressure fluctuations in the air caused by

The lower the TL of an assembly, the greater the sound insulation provided by it

The STC of an assembly can be improved if we make it heavier

STC of a 2 x 4 wood stud wall with ½” gypsum board each side = 37. To improve it, we can…

NRC stands for

Sound originating within a room can only be reduced by using sound-absorbing materials

Sound-absorbing materials(acoustical materials) have a sound-absorption co-efficient of

The sound-absorptive coefficient of an assembly =

A closed window is the perfect acoustical absorber because it does not reflect any sound

The sound pressure that corresponds to the sensation of pain in the ear is approx

Although sound pressures are small, their range is extremely large

Massive heavyweight assemblies are horrible sound insulators

Light gauge steel members are increasingly used as blocking/backing for handrails, upper cabinets, or any other secured material or assembly
