An improvement to motorcycle intercom communications between the motorcycle driver and passenger providing for stereo listening in each of both right and left helmet earphones wherein intercom communications may be had through microphones always activated located proximate the mouth of both driver and passenger where when initiating speaking over the microphone, the stereo output of one side of the earphones is reduced by approximately one/half while the stereo output of the other side earphones is terminated completely and the intercom conversation is heard in full over that single side of earphones. Upon the termination of the intercom conversation, the invention circuitry returns both sides of earphones to the pre-existing level of stereo output. The above is accomplished by dividing all sounds which come in over the microphone into a low and high frequency range separated by an audio speaking range wherein the outputs of the low and high frequency range filters are constantly sampled and compared with the energy output of the audio speaking range of frequencies. When the energy in the speaking range of frequencies exceeds the energy in the low and high frequency range, such is indicative that a party is speaking into the microphone and the circuit automatically terminates the output of one earphone, reduces the other by half, and injects the intercom on the earphone whose stereo had been terminated.

Noise cancelling microphone construction for placement in a full coverage style helmet to secure and hold a noise cancelling microphone in the plenum between the inner liner and outer shell of the helmet, the construction having a front boot and a rear boot. The front boot has a speech receiving front open sleeve leading to front ports of the microphone, a flat annular flange attached to a cylindrical end of the front sleeve, and a second sleeve attached at one of its cylindrical ends to the other side of the flange, the second sleeve securing the front part of the microphone, the flange and second sleeve encompassing an opening in the helmet inner liner. A box formed on the front sleeve receives noise in the helmet environment, passes the noise through an opening in the annular flange and through the opening in the helmet inner liner. The rear boot has a cylinder with one closed end to hold and secure the rear part of the microphone, and an elongated sound passageway attached to its outside communicating with the cylinder interior through an opening. The sound passageway conducts noise from the front boot box to the rear ports of the held noise cancelling microphone.

An improved motorcycle intercom communications system between the motorcycle driver and passenger providing for stereo of listening from a radio, cassette player, or the like in each of both right and left helmet speakers wherein intercom communications may be had through microphones always activated located proximate the mouth of both driver and passenger, where when initiating speaking over the microphone, the stereo output of both right and left speakers of the driver's and passenger's helmets is terminated completely and the intercom conversation is heard in full. Upon the termination of the intercom conversation, the invention circuitry returns both sides of speakers to the pre-existing level of stereo output. The above is accomplished by dividing all sounds which come in over the microphone into a low frequency range and an audio speaking range wherein the output of a low frequency range filter is constantly sampled and compared with the energy output of the audio speaking range of frequencies. When the energy in the speaking range of frequencies exceeds the energy in the low frequency range, such is indicative that a party is speaking into the microphone and the circuit automatically terminates the output to both helmet speakers and injects the intercom on the helmet speakers.

A noise cancelling microphone for use in noisy environments is disclosed wherein noise entering the front portion of the microphone housing to impinge upon the microphone cartridge diaphragm is also permitted to enter proximate the rear portion of the microphone housing through strategically located inlet openings. This allows noise to impinge upon the back surface of the microphone cartridge diaphragm to effect a cancellation of diaphragm vibrations. These strategically located inlet openings at the top and the bottom of the rear of the microphone housing are situated so as to be directionally orientated towards the greatest source of the noise, namely orthagonal to the directional line of the front inlet openings and out of the path of the incoming air. The size and number of the top and bottom rear inlet openings are regulated and situated so that as the microphone is used in such a setting as a motorcycle rider, they are vertically oriented since the greatest source of noise (outside of horizontal wind) is above or below the operator.

A helmet headset system for use with an audio system and a helmet. The helmet headset system comprises a mount for mounting to the helmet, and first and second audio signal conduits, e. g. each comprising a coil cord, and each having first and second ends. The first end of the first audio signal conduit is coupled to the mount. The first end of the second audio signal conduit is detachably coupled to the second end of the first audio signal conduit, and the second end of the second audio signal conduit is detachably coupled to the audio system. In a related aspect, the system may comprise a single, detachable audio signal conduit. Related methods also are provided.
