This study investigated the influence of whole-body vibration (delivered via the floor and the seat on which participants were situated) on preferred equalization for binaural recordings of musical sound reproduced via an automotive audio system. It was hypothesized that low-frequency musical sound signals (below 80 Hz) reproduced as structural vibration would shift an observer's preferred level of low-frequency sound in the binaurally-captured automotive audio reproduction. To test this hypothesis, an adaptive staircase method was used to track preferred levels of low-frequency audio reproduced binaurally via headphones in two different vibration conditions, nominally termed high-vibration and low-vibration (the latter being 12 dB lower than the high-vibration level). Data from 6 observers showed that preferred levels for headphone-delivered low-frequency audio signals were reduced as vibration levels were increased for all 4 musical programs tested. The results of this study imply that such vibration should not be ignored in future use of binaural simulation for the evaluation of automotive audio reproduction.
