Why Isolation (Soundproofing) is Important

Isolation (also known as soundproofing) is important for a variety of reasons.  The most commonly recognized reason is to stop sound from bothering other people in the house or other people outside the room and the house/building. A more important reason to soundproof is to stop sound from getting INTO the room.  Why is this […]

Speaker Boundary Interference Response (SBIR)

SBIR (Speaker Boundary Interference Response) – This is a term to describe how the proximity of a speaker to a hard boundary (wall/ceiling/floor) will change the response, especially in the low end. This is something that not a lot of people understand nor consider when planning a room. Sound radiates from a driver in different […]
