Abstract: In many loudspeaker systems high levels of air compression pressure result in turbulent noise if there are any air leaks. Traditional measurement techniques have difficulty identifying this particular defect because the resulting noise is wideband with low-power density, which is easily masked by environmental noise. A new technique designed to detect this kind of defect is based on asynchronous demodulation and envelope averaging. By accumulating the total energy of air leak noise, detection sensitivity increased by 20 dB for a 1-second measurement interval. This approach exploits the spectral information between the higher-order harmonics.

AB - In many loudspeaker systems high levels of air compression pressure result in turbulent noise if there are any air leaks. Traditional measurement techniques have difficulty identifying this particular defect because the resulting noise is wideband with low-power density, which is easily masked by environmental noise. A new technique designed to detect this kind of defect is based on asynchronous demodulation and envelope averaging. By accumulating the total energy of air leak noise, detection sensitivity increased by 20 dB for a 1-second measurement interval. This approach exploits the spectral information between the higher-order harmonics.
