World Class Acoustics, Inside and Out

Avalon’s refined acoustic repertoire spans inside and out. Through Sport+, passengers receive a concerto of exciting, natural sounds through a new exhaust system with sport modified baffles, an Intake Sound Generator (ISG), Active Noise Control (ANC), and Engine Sound Enhancement (ESE).

ISG amplifies the engine’s air inhalation sound to create robust vocalization and, on the exhalation end, the all-new exhaust with baffle tuning ups the sound character at start-up, idle, and acceleration. ANC and ESE work to cancel any unwanted exterior noise while simultaneously enhancing engine sound via the JBL multimedia system’s in-cabin speakers. Exceptional engine notes at start-up are also enhanced; a hearty “flare” of sound occurs right before idle upon start-up. At wide-open-throttle acceleration, more engine grunt is heard throughout the rev range.

For all its added energetic vocalization, Avalon never ceases to deliver a civilized, library-quiet interior, if desired. Road noise and engine droning have been culled while cruising quietness and engine sound have been improved. Its TNGA platform utilizes additional seals where front fenders meet front doors and where the doors merge at the B-Pillar. More sound absorption material is found in the engine bay, within the carpet pad, under the floor, and in the wheel well liners. The exterior rearview mirrors not only reduce drag, but also wind noise, making for an extremely quite environment for all.
