Abstract: A conventional hearing aid for a hard-of-hearing person has a microphone input for sensing sounds or voice communication. In a high noise environment, a somewhat remotely located speaker wishing to communicate with the person talks into a microphone input to a transmitter so that his spoken word is transmitted as a modulated carrier wave. The hard-of-hearing person is provided with a receiver which receives and detects the modulated carrier wave. The detected signal is applied to a transducer to reproduce the spoken word. A hollow elongated conduit comprising a flexible tube having a small bore extending therethrough, conducts the audible sound representing the spoken word from the transducer to the microphone input of the hearing aid, thus enabling the wearer of the hearing aid to hear the remotely spoken sounds of a lower level than the ambient noise while at the same time hearing the ambient noise. The conduit may contain a wire for acoustic loading and/or structural strength.
