Direct Sound Compensation

The combination of gain provided by the hearing instrument and un-amplified environmental sounds that enter directly through the ear canal can lead to undesired effects particularly in open canal fittings. To overcome this phenomenon and achieve the best possible sound quality, Phonak Target™ developed Direct Sound Compensation to supplement the pre-calculation. This unique algorithm automatically ensures that amplification is not applied for frequencies that are already audible directly through the vent. This dynamic process insures that both direct and amplified sounds combine optimally for a more natural sound quality.
