摘要:
Disclosed is a method of determining in real-time an estimate of a Sound Pressure Level or Sound Exposure corresponding to sound produced in an acoustic environment by multiple loudspeakers of a sound system in response to an input signal to the sound system. The method comprises determining in real-time the estimate of the Sound Pressure Level or Sound Exposure on the basis of the input signal. The sound system is a level-calibrated sound system. Also disclosed is a real-time sound level estimator. Also disclosed are a method and a real-time sound level estimator where the estimation is based on an approximation of system properties based on microphone measurements, or established for multiple listening positions, respectively. Also disclosed are methods of calibrating and monitoring a sound system and calibration and monitoring devices therefore.

A method of analyzing and displaying spectral-dynamic properties of an audio signal, including measuring a level over time in multiple neighboring frequency-bands based on the audio signal; calculating spectral-dynamic characterizing values based on two or more statistics of a distribution of the measured levels within each of the frequency-bands; and displaying a graphical representation of the spectral-dynamic characterizing values as a function of frequency.

摘要:
A method for determining spatial relations in a loudspeaker system comprising a central controller, multiple loudspeakers and multiple microphones. The method comprises using the multiple loudspeakers to produce sound and using the multiple microphones to measure the produced sound. Spatial relations between the loudspeakers are determined based on the measured sound, and the multiple loudspeakers are assigned to loudspeaker zones based on the determined spatial relations. Audio of the multiple loudspeakers is controlled in accordance with the assigned loudspeaker zones. Further, a method for verifying the installation of such a loudspeaker system, and a loudspeaker system with zoning and/or verification.
