摘要： A system and method to detect PASS-type device audio alarm signals and to locate such devices in alarm in a public building, airport, sports stadium or other structure which can include a system to measure speech intelligibility. Time and frequency domain analysis are carried out to establish the pressure of PASS-type device audio output signals.

摘要： A system and method to detect and remediate unacceptable levels of speech intelligibility evaluates received test audio transmitted across and received in a space or region of interest. Intelligibility is improved by altering the rate, pitch, amplitude and frequency bands energy during presentation of the speech signal.

摘要： A measurement system and method combine an audio announcement system with a plurality of spaced apart wirelessly coupled devices which evaluate speech intelligibility of audio output from loudspeakers of the audio announcement system. Processing can take place at some or all of the devices as well as at a common control element. Evaluations can be based on use of a method which maps to a Common Intelligibility Scale.

摘要： A method of optimizing the low frequency audio response emanating from a pair of low frequency transducers housed within a cabinet. The low frequency transducers are electrically connected to a power amplifier and source of audio content. The resonant frequency (Fs) and amplitude (Q) are characterized as to the high-pass pole of the low frequency transducers as they are mounted within the cabinet. An equalizer is placed between the amplifier and source of audio content for canceling the complex pole of the low frequency transducers and for establishing a new complex pole at a cut off frequency below which the sound generated by the low frequency transducers will diminish.

摘要： A speaker system which includes a housing and a linear array of a plurality of sound-generating transducers. A housing is in the form of a cylinder having a longitudinal axis and substantially circular cross-section. The linear array of sound-generating transducers are mounted upon a substantially planar chord configured within a sidewall of the cylinder.
