Organization: JSA
Publication Date: 20 June 2019
Status: active
Page Count: 59
ICS Code (Acoustic measurements and noise abatement in general): 17.140.01
ICS Code (Noise with respect to human beings): 13.140
scope:

This Standard defines the basic quantities to be used for the description of environmental noise and describes basic assessment procedures.

Environmental noise refers to (undesired) noise in general living environment.

NOTE 1 Annexes JA and JB provide outlines of provisions of JIS C 1509-1 regarding frequency weightings A and C, and time weightings F and S that are used as a basis for environmental noise assessment.

NOTE 2 Annexes JC to JJ provide outlines of measuring methods for different types of noise sources that are actually used in Japan to assess environmental noise in accordance with the relevant laws and regulations such as the Noise Regulation Act and the Basic Environment Act.

NOTE 3 The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 1996-1:2016 Acoustics-Description, measurement and assessment of environmental noise-Part 1: Basic quantities and assessment procedures

ISO 1996-2:2017 Acoustics-Description, measurement and assessment of environmental noise-Part 2: Determination of sound pressure levels (Overall evaluation: MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
