The Influence of Acoustic Environment on the Threshold of Audibility of Loudspeaker Resonances

Resonances in loudspeakers can produce a detrimental effect on sound quality. The reduction or removal of unwanted resonances has therefore become a recognized practice in loudspeaker tuning. This paper presents the results of a listening test which has been used to determine the audibility threshold of a single resonance in different acoustic environments: headphones, loudspeakers in a standard listening room and loudspeakers in a car. Real loudspeakers were measured and the resonances modelled as IIR filters. Results show that there is a significant interaction between acoustic environment and programme material.
