  • Patent number: 11895467
    Abstract: Secondary path measurements and associated acoustic transducer-to-eardrum responses are obtained from test subjects. Both a least squares estimate and a reduced dimensionality estimate are determined that both estimate a relative transfer function between the secondary path measurements and the associated acoustic transducer-to-eardrum responses. An individual secondary path measurement for a user is performed based on a test signal transmitted via a hearing device into an ear canal of the user. An individual cutoff frequency for the individual secondary path measurement is determined. First and second acoustic transducer-to-eardrum responses below and above the cutoff frequency are determined using the individual secondary path measurement and the least squares estimate. A sound pressure level at an eardrum of the user can be predicted using the first and second receiver-to-eardrum responses.

  • Patent number: 11881819
    Abstract: A sound system includes a sound source having an analogue audio signal output and a sound volume control; signal amplifier apparatus (10) comprising an analogue signal input (12) configured to be coupled to the analogue audio signal output of the sound source, an analogue signal output (18) and an amplifier module (62) coupled between the signal input and the signal output. The amplifier module (62) has a fixed amplification gain within a range of 10 to 12 decibels. Control of the audio signal is effected solely by the sound volume control of the sound source. The amplifier module (64) also provides a fixed gain bass boost of 6 decibels. The system provides linear amplification and allows a user to reduce the volume of the sound source, which significantly reduces signal distortion. Volume control is at the sound source and not at the amplifier module, which optimises amplification quality and reduces the power requirement of the amplifier apparatus (10).
