Acoustical design in courtrooms focuses primarily on two things: maximizing speech intelligibility within the room and minimizing disruptive noise from interfering with the court proceedings. In some situations, such as with individuals with compromised hearing or in rooms with poor acoustical performance, although we may hear a person speaking it is difficult to decipher what they are saying. Speech intelligibility refers to the ability to clearly understand each word being spoken. Individuals who suffer from common noise-induced hearing loss may have decreased sensitivity in the 4,000Hz area. this can play a significant role in the ability to understand speech in, as the consonants crucial to understanding spoken word reside in the 2,000 to 6,000Hz range. Fortunately, appropriate acoustical design will support and enhance speech intelligibility within courtrooms and supply the required clarity for such a space.
