Introduced in 2009, Acoustically Optimized Vent (AOV) was created to streamline the custom hearing aid ordering process. AOV takes into account the unique characteristics of each client, including the audiometric configuration, risk of feedback, likelihood of occlusion, benefit of direct sound, and the need for low-frequency gain.

1 天前 · Need a refresher on AOV? Well, the AOV is a Phonak proprietary, multidimensional-weighted algorithm that sets an optimized target ‘acoustic mass’. By ‘optimized’ we mean the precise AVM needed for size and performance for a patient, based on their audiogram. The vent can then be modelled to reach the target AVM computed by the AOV algorithm.

AOV in the new Exélia CIC Petite is a Phonak innovation that takes the guesswork out of vent selection, using a sophisticated, new process to guarantee individualized, optimal venting in the smallest instrument possible with natural sound quality.
