Abstract: A sound masking system according to the invention is disclosed in which one or more sound masking loudspeaker assemblies are coupled to one or more electronic sound masking signal generators. The loudspeaker assemblies in the system of the invention have a low directivity index and preferably emit an acoustic sound masking signal that has a sound masking spectrum specifically designed to provide superior sound masking in an open plan office. Each of the plurality of loudspeaker assemblies is oriented to provide the acoustic sound masking signal in a direct path into the predetermined area in which masking sound is needed. In addition, a loudspeaker assembly is configured as a bolt and slip-nut threading system for ease of installation. The exterior surface of the loud speaker "bolt" and the interior surface of the locking nut contain axially oriented, reciprocal regions with and without threads. In operation, the regions of the nut without threads are oriented to correspond to the regions of the bolt with threads. The nut is then slid along the bolt until the desired placement position is reached and locked in place with a half turn of the nut or less. An interference pin may also be used to provide positive locking of the nut at any position.

Abstract: A system and method of providing sound reinforcement in a classroom, an office, a conference room, an auditorium, or any other suitable venue. The system includes at least one microphone, a receiver, a sound masking signal generator, a system controller, and a plurality of spatially distributed loudspeakers. The microphone detects the speech of a talker, generates at least one voice signal corresponding to the detected speech, and provides the generated voice signal to the receiver. The sound masking signal generator generates at least one sound masking signal having a specified sound masking spectrum. The system controller receives the voice signal and the sound masking signal from the receiver and the sound masking signal generator, respectively, and provides the voice and sound masking signals to the loudspeakers over respective channels. The loudspeakers emit acoustic voice and sound masking signals simultaneously and directly into the venue to obtain a more uniform sound field coverage for the acoustic voice signals and more uniform levels of the acoustic sound masking signals throughout the venue.
