    Operations

    Operational Requirements

    Cosmonaut hearing protection set, Acoustic noise monitoring system (two-channel sound analyzer BK 2260), Laptop, Acoustika kit.

    Operational Protocols

    Recording of voice information on the ISS and interference in the communication link during communication sessions of the crew with the ground for further analysis. Measurement of characteristics of ISS acoustic medium and onboard communication links qualifying voice transmission and acoustic load on the crew during communication coverage.

    Results/More Information

    Recommendations to improve the onboard communication quality with concurrent reduction of volume of audio signals, that will allow to reduce the acoustic load on cosmonauts' ears. Recommendations to add requirements aimed at assuring reliability of the audio communication concerning articulation and articulation characteristics of speech transactions to the operational requirements for acoustic conditions in the ISS RS modules. Acquisition of data to develop computer techniques to remove interference from a speech signal.
