APPARATUS AND METHOD FOR DETERMINING A ROOM DIMENSION ESTIMATE

摘要

An apparatus for determining a room dimension estimate comprises a receiver (101) providing an acoustic room response e.g. generated from acoustic measurements. A peak detector (103) detects a set of peaks in the acoustic room response in a frequency interval having an upper frequency of no more than 400 Hz. A store (107) comprises a set of peak profiles with associated room dimension data, and an estimator (105) determines the room dimension estimate from the associated room dimension data and a comparison of the set of peaks to the peak profiles. The estimator may perform the steps of first finding a matching peak profile for the set of peaks from the set of peak profiles; extracting first room dimension data associated with the matching peak profile(s) from the store; and determining the room dimension estimate in response to the first room dimension data. The peak profiles may represent calculated Eigenfrequencies.
