GSSH-A-18E

GSSH-A-18E headset for aircraft communication

The GSSH-A-18E is an aviation headset with medium noise protection, designed for two-way voice communication in aircraft and ground support environments. It is used where the operator must clearly hear radio or intercom audio and transmit speech despite engine noise, airflow, vibration and other acoustic interference. The headset includes two earphones, a noise-resistant microphone, a spring headband and a connection cable. It is suitable for use by flight crew members, technical personnel or operators working with aircraft communication systems.

Speech transmission through the GSSH-A-18E microphone

The GSSH-A-18E is equipped with a noise-resistant microphone mounted on an adjustable holder. The microphone is positioned close to the operator’s mouth, which helps maintain speech intelligibility in noisy conditions. In many headset configurations of this class, a DEMSh-type dynamic microphone capsule may be used, depending on execution and documentation. The microphone is intended for aircraft communication circuits, where stable speech transmission is more important than studio-quality sound. Correct positioning of the microphone is important during operation, because poor placement can reduce speech clarity even if the headset itself is serviceable.

Audio reception in the GSSH-A-18E earphones

The headset uses two earphones installed in sound-protective housings. They receive audio from onboard radio communication, intercom or self-monitoring circuits, depending on the connected equipment. The earphone assemblies are mounted on a spring headband, allowing the headset to sit firmly on the head while keeping both earphones in contact with the ears. This is important in aircraft environments, where loose fit immediately reduces noise protection and speech readability. The headset is designed for practical service use, not for occasional light-duty audio listening.

Noise protection of the GSSH-A-18E

The GSSH-A-18E is designed for work in acoustic noise environments with a total noise level up to 115 dB. Its medium noise protection helps reduce the effect of surrounding noise while still allowing the user to work with communication equipment for long periods. The headset is intended to provide speech intelligibility not worse than the stated aviation communication requirements under noise conditions. It is suitable for cockpits, aircraft cabins, maintenance areas and ground service tasks where noise is high, but a heavier helmet-type communication system is not required.

Shielded cable and GSSH-A-18E export execution

The “E” index in the GSSH-A-18E designation is associated with export / shielded execution, depending on supply documentation. In this version, special attention is given to cable shielding and protection from radio-frequency and high-frequency interference. This matters near powerful onboard transmitters and aircraft communication equipment, where unshielded wiring can pick up interference and degrade speech transmission or reception. When ordering the headset, the exact execution and connector type should be checked, because the same headset family may be supplied with different cable and plug configurations.

Cable-mounted unit on the GSSH-A-18E

A cable-mounted unit may be installed on the GSSH-A-18E connection cable. Depending on the execution and connected equipment, this unit can perform matching, amplification or interface functions for use with aircraft intercom and communication circuits. Such a block is especially relevant when the headset must work with high-impedance audio paths or specific aircraft communication equipment. For replacement supply, the cable unit should not be treated as a minor accessory. Its presence, type, wiring and connector configuration can determine whether the headset will work correctly with the target aircraft system.

Operating conditions and supply of GSSH-A-18E

The GSSH-A-18E is intended for demanding aviation use and is designed to remain serviceable across a wide temperature range, humidity exposure, vibration and mechanical loads typical of aircraft operation. Before supply or installation, the headset should be checked by designation, execution, plug type, cable condition, microphone condition, earphone operation and documentation. If the headset is ordered as a replacement for an existing aircraft communication set, the buyer should confirm the aircraft type, intercom system, connector standard and whether oxygen mask compatibility or a specific cable-mounted matching unit is required.
