When attempting to soundproof a room, there are various levels of sound isolation and many different types of materials available. How far you go with your construction depends mostly on they type of sound you wish to abate. The acoustic solution needs to be designed around your specific application. Is it the noise of an industrial plastic shredder or speech from an adjacent office? This brief demonstration on how to block sound shows using different building materials affects the transmission of sound.

 A typical wall construction consists of two layers 1/2″ gypsum applied to either side of a 2×4 wood or metal stud. Many of the walls for residential and commercial interiors will lack insulation in the cavities. This type of construction will yield an STC (Sound Transmission Loss) around 31 – 33. By simply adding a layer of fluffy glass fiber insulation to the cavity, the STC will increase by 4-5 points and prevent sonic resonance. Additionally, a layer of mass loaded vinyl barrier will add another 4-5 points. We have prepared a simple video demonstration to illustrate how using multiple layers of common building materials will improve STC values.

Meeting Room Acoustics

Meeting space planning tends to focus on the visual element. Poor acoustics — which can negatively impact communication — are typically discovered only after the room is complete. Fixing acoustic problems can be costly and time-consuming. When planning and equipping meeting spaces, technology managers need to pay att

SIA Acoustics

The Mount Sinai Medical Center--a working hospital, not a venue--was host to over 1,400 guests for its 20th anniversary Crystal Ball gala. The annual fundraising event is held in the hospital’s acoustically-challenging I.M. Pei-designed atriums where conditions are far from ideal for event production and clear speech and high-quality sound are concerns: the spaces are constructed of concrete, steel and glass. Additionally, the design team was faced with a situation where the primary function of the location was not event-oriented but purely medical. A solution with minimal impact on the hospital itself was of the utmost importance.
