SOUND MASKING IN OPEN-PLAN SPACES USING NATURAL SOUNDS |
摘要 |
A system, method and program product for generating sound masking in an open-plan space. A method is disclosed that includes: establishing a set of acoustic criteria for the space that specifies minimum output levels at a set of specified frequencies; mixing sound samples to create an audio output stream for use as sound masking when broadcast over at least one speaker using a power amplifier; and processing the audio output stream, wherein the processing includes: analyzing the audio output stream with a spectrum analyzer to determine if the minimum output levels at the set of specified frequencies are met; and level adjusting the audio output stream with an equalizer to ensure that minimum output levels at the set of specified frequencies are met but do not exceed a given threshold above the minimum level. |
