Scope

GB/T 5265-2009 is the English-translated version of 声学水下噪声测量.

GB/T 5265-2009 is the Chinese standard "Acoustics - Measurement of underwater noise". Its scope clause reads: This standard specifies the conditions and methods of measurement of underwater noise, so that the measurement data obtained results can compare and contrast.

This standard applies to the measurement of underwater noise deep ocean, shallow sea, the harbor and the bay and other premises. NOTE. river, lakes and other underwater noise measurements refer to this standard.

This standard is applicable frequency range. 20Hz ~ 20kHz.

This standard specifies the measurement results may be sonar system design, underwater acoustic equipment operating range analysis and projections, ship underwater radiated noise measurement Analysis of the amount of background correction to provide data; underwater ocean noise measurement as an acoustic remote sensing methods can be used to estimate the relevant environmental parameters, Such as wind speed, waves, earthquakes, tsunamis and the like; biological monitoring underwater noise and man-made noise sources; can also be used to study the underwater noise generation, propagation The physical mechanism and statistical characteristics. Its clauses include terms and definitions.

This standard specifies the conditions and methods of measurement of underwater noise, so that the measurement data obtained results can compare and contrast.

This standard applies to the measurement of underwater noise deep ocean, shallow sea, the harbor and the bay and other premises.

NOTE. river, lakes and other underwater noise measurements refer to this standard.

This standard is applicable frequency range. 20Hz ~ 20kHz.

This standard specifies the measurement results may be sonar system design, underwater acoustic equipment operating range analysis and projections, ship underwater radiated noise measurement

Analysis of the amount of background correction to provide data; underwater ocean noise measurement as an acoustic remote sensing methods can be used to estimate the relevant environmental parameters,

Such as wind speed, waves, earthquakes, tsunamis and the like; biological monitoring underwater noise and man-made noise sources; can also be used to study the underwater noise generation, propagation

The physical mechanism and statistical characteristics.

3 Terms and Definitions

GB/T 3947-1996 and established the following terms and definitions apply to this standard.

3.1

Due to natural causes, such as waves, turbulence, thermal disturbance caused by noise in the ocean.

NOTE. In addition to biological noise, seismic noise, rain noise, noise and other man-made ocean noise is called the noise, the former is called ambient noise (ambient noiseofthesea).

3.2

For receiving acoustic-electric water acoustic signal transducer.

Note. Due to the working principle, structure and characteristics of different types have different hydrophones. As classification according to the principle, piezoelectric hydrophone, electromagnetic hydrophone, light

Fiber hydrophone, MEMS hydrophone like.

3.3

Secondary standard water is used as the sound of water measured hearing. Measuring hydrophone hydrophone is usually a standard or a standard transmitter comparative method calibration.
