Description

The IOA Southern Branch presents:

BS 4142:2014 – How do the Results of the Objective & Reference Methods for Tonal & Impulsive Noise compare to your Professional Opinion?

An evening meeting organised by the Southern Branch including expert assistance and guidance from:

Mike Breslin (ANV Measurement Systems)

BS 4142: 2014 advises that certain acoustic features can increase the significance of impact of a sound and that where such features are present a character correction should be added to the Specific Sound to obtain the Rating Level. The Standard advises that this can be approached in three ways a) Subjective Method b) Objective Method for Tonality and c) Reference Method.

A number of commercial sounds have been recorded and these will be presented to the audience who will be asked to submit their subjective assessments of tonality and impulsiveness in accordance with Section 9.2 of BS 4142:2014.

The Subjective, Objective and Reference Methods will be explained during the course of the meeting. However, being familiar with Section 9.2 of the Standard (which explains the Subjective Method) prior to the meeting is highly recommended.

The results of the Subjective Assessments for each sound will be compared to the results of the Objective and Reference Methods. The comparison will be done statistically and the presenter will not be making individuals’ assessments public.
