What is an acoustical ceiling?
• Acoustics is usually very broadly defined as “the science of sound.” The term “Room Acoustics” can be more narrowly defined as the shaping and equipping of an enclosed space to obtain the best possible conditions for faithful hearing of wanted sound and the direction and the reduction of unwanted sound. It deals primarily with the control of sound which originates within a single enclosure, rather than its transmission between rooms. • • In addition to reducing the undesirable background noises that originate withing a room, the acoustical objective often includes preservation of the wanted sounds. For example, any space considered to be speech or music room — upper grade classrooms, assembly halls, or wherever we are communicating to an audience of some kind, requires faithful reproduction of wanted sound. The techniques are retention and reinforcement of useful sound reflections. In short, we control sounds for communication with reflective surfaces, and we control reverberation a
