METHOD FOR FITTING A DIGITAL HEARING AID, HEARING AID AND COMPUTER PROGRAM PRODUCT
20230044076 · 2023-02-09 ·

A method fits a digital hearing aid having an input transducer, a signal processing device and an output transducer. The signal processing device is configured to form an evaluation unit, a comparator unit, and a pre-amplification unit. An acoustic test signal is generated by an external testing device while the hearing aid is worn by a hearing-aid wearer. A digital test input signal is generated by the input transducer on the basis of the acoustic test signal. A sound pressure-dependent test quantity is determined on the basis of the digital test input signal by the evaluation unit. A deviation between the sound pressure-dependent test quantity and a reference quantity stored in the signal processing device is determined by the comparator unit. A pre-amplification by the pre-amplification unit is adjusted on the basis of the determined deviation.

Earphone cord containment adaptor and holder
11558684 · 2023-01-17 ·

A cord containment adaptor can be adaptively anchored or fixed to or removed from an earphone cord of a set of earphones by hand via an anchor slot of the adaptor. The anchor slot can have a frame or structure that may have multiple earphone cord entrapment chambers and/or an offset or non-linear path leading to an earphone cord entrapment chamber or chambers to help anchor the cord containment adaptor on the cord segment to prevent inadvertent dislodgement of the cord containment adaptor from the earphones. The structure of the anchor slot can be rigid and serves to firmly grip or compress earphone cord segments positioned between gapped-apart opposing sidewalls within the anchor slot. Entrapment chambers of the anchor slot are connected to every other entrapment chamber via cord passageways through which an earphone cord segment can pass. The cord containment adaptor may contain cord containment slots separate from the anchor slot. When a cord containment adaptor is anchored via the anchor slot, earphone cord segments can be gripped into slots in a manner that contains loose cord ends and helps prevent tangling of earphone cords when the earphones are stored or not in use. The adaptor can remain fixed to an earphone cord segment during audio listening by a user and during storage of an earphone set.
