  • a first hearing assistance device configured to be worn in a first ear of a wearer; and

    a second hearing assistance device configured to be worn in a second ear of the wearer,wherein the first hearing assistance device includes a first processor configured to compute a first gain estimate for a first sound played at the first ear using first noise reduction calculations based on a first received sound at the first hearing assistance device, combined with second coded noise reduction calculations based on a second sound received at the second hearing assistance device, the second coded noise reduction calculations transferred wirelessly from the second hearing assistance device at a bit rate that is reduced by increasing a level of quantization from a rate necessary to transmit the information prior to coding.
