introduction
This specification is based on JJF 1071-2010 "Rules for the Compilation of National Metrology Standards and Specifications" and GB/T.20001.1-
2001 "Standard Preparation Rules Part 1.Terminology" given rules and formatting.
This specification replaces JJF 1034-2005 "Acoustic Metrology Terms and Definitions". Compared with JJF 1034-2005, the main technical changes are as follows.
---Deleted sound [wave], longitudinal wave, transverse wave, free traveling wave, plane wave, cylindrical wave, spherical wave, wave front
(Wavefront), spectrum (spectrum), line spectrum, continuous spectrum, spectral density, power spectral density, A [weighting] sound [pressure] level,
Equivalent [continuous A weighting] sound [pressure] level, main axis, harmonics, narrowband noise, nominal frequency, digital audio frequency, sampling
Sample frequency, folding frequency, in-band frequency, upper-band frequency, out-of-band frequency, rise time, fall time, sound
Process, octave, cent, note, rhythm, chromatic scale, transducer, passive transducer, active transducer, linear transducer,
Reversible transducer, reciprocal transducer, transmitter, receiver, loudspeaker, reciprocal calibrator, underwater acoustic probe and
A total of 45 items for comparison and calibration;
---Modified acoustic measurement, sound field, free field, diffusion [sound] field, sound velocity, particle displacement, particle velocity,
115 items including static pressure, sound pressure, sound intensity [degree], frequency weighting, time weighting, and level;
---Added subacoustics, audiology, language acoustics, music acoustics, architectural acoustics, acoustic measurement, audible sound,
360 items such as environmental noise and self-generated noise;
---Added 195 symbols and abbreviations such as bandwidth indication value, filter attenuation, sound absorption, [channel] crosstalk attenuation, etc.;
---The items are arranged according to the professional classification of acoustic measurement.
The previous releases of this specification are as follows.
---JJF 1034-2005 "Acoustic Metrology Terms and Definitions";
---JJF 1034-1992 "Acoustic Metrology Terms and Definitions".
