Characterizing the Amplitude Response of Loudspeaker Systems
The amplitude response of a loudspeaker system is characterized by a series of spatially averaged measurements. The proposed approach recognizes that the listener hears three acoustical events in a typical domestic environment: the direct sound, the early arrivals and the reverberant sound field. A survey of 15 domestic multi-channel installations was used to determine the typical angle of the direct sound and the early arrivals. The reflected sound that arrives at the listener after encountering only one room boundary is used to approximate the early arrivals, and the total sound power is used to approximate the reverberant sound field. Two unique directivity indices are also defined and the in-room response of the loudspeaker is predicted from anechoic data.
