Self-Assessment «AudEval» App

The «AudEval» App provides (1) a high-resolution auditory evaluation for 56 frequencies between 55–7,040 Hz that can be carried out in the users' home environment; and (2) individually organized, hearing-loss specific training sessions that help to improve auditory thresholds and speech intelligibility (languages: English, French, German, and Spanish).

Auditory Evaluation

Auditory Tests determine the users' hearing threshold for a given frequency (tone) for either the left ear, the right ear, or both ears together. The Test presents the tone of the chosen frequency several times while successively adjusting loudness. The procedure starts with the user-defined initial loudness (e.g., -25.5 dB) and reduces loudness in steps of -1.5 dB until the user is unable to detect any sound. All this is done for 56 frequencies between 55–7,040 Hz (7 octaves; 8 tones per octave).

Training 1: Auditory Thresholds

Training 1 loops through 56 frequencies between 55–7,040 Hz (7 octaves; 8 tones per octave); the tone duration is 8 seconds with pre-specified loudness and for the selected ear(s). Please note: any auditory training will show the desired effect only if the training sessions are repeated on a regular basis (e.g., twice per day for 15 minutes).

Training 2: Speech Intelligibility

Training 2 presents a standard text of 60 seconds duration with background noise at a pre-specified loudness and for the selected ear(s). Focus is laid on speech intelligibility: Users begin with a comfortable loudness and concentrate themselves on understanding each single word. Subsequently, users may reduce loudness and repeat the training twice a day for 15 minutes, noting down the training time and the intensities used. Available languages are English, French, German, and Spanish.
