Overview

ISO 15619:2013 specifies standardized measurement methods and requirements for exhaust silencers installed on reciprocating internal combustion engines. It covers both laboratory (engineering and survey methods) and site measurements to determine acoustic and aerodynamic performance parameters such as sound power level of exhaust noise, insertion loss, and power loss ratio. The standard supports consistent, repeatable testing and reporting for silencers used with engines within the scope of ISO 3046 series.

Key topics and technical requirements

Measurement scope

Sound power level (A‑weighted or frequency bands) using sound pressure
Insertion loss (A‑weighted or frequency bands)
Power loss ratio (aerodynamic matching)
Optional transmission loss and pressure loss procedures (see informative annex)

Measurement methods

Laboratory engineering method (accuracy grade 2) - higher precision
Laboratory/site survey method (accuracy grade 3) - for comparative or field tests

Measurement uncertainty

Engineering method: standard deviation of reproducibility ≤ 1.5 dB (A‑weighted)
Survey method: standard deviation of reproducibility ≤ 4.0 dB (A‑weighted)
One‑third‑octave and octave band reproducibility limits are defined in the standard

Test setup and environment

Requirements for test environment, background noise criteria, and acoustic adequacy
Instrumentation and calibration procedures
Installation and operation of the engine/noise source for laboratory and site testing

Measurement & calculation

Detailed measurement procedures, microphone locations (90° vs 45° directions), and correction methods
Calculation methods for sound power level, insertion loss, and power loss ratio

Reporting

Required information to record about silencer, engine, instrumentation, acoustical environment, and test results
Test report and annexed procedures for environment qualification and pressure‑loss measurement

Applications and who uses it

ISO 15619:2013 is relevant to:

Engine manufacturers and OEMs verifying acoustic matching between engines and silencers

Silencer designers and suppliers validating product performance (insertion loss, pressure loss)

Acoustic test laboratories performing standardized laboratory and site measurements

Regulatory bodies and certifiers assessing compliance with noise/emissions requirements

Acoustical and mechanical engineers involved in noise control, product development, and field diagnostics

Practical uses include acceptance testing, engineering design verification, comparative field surveys, and procurement specifications for exhaust silencers.
