Abstract

Overview

ISO 11546-1:1995 - "Acoustics - Determination of sound insulation performances of enclosures - Part 1: Measurements under laboratory conditions (for declaration purposes)" specifies laboratory methods for determining the sound-insulation performance (insertion loss) of small machine enclosures. The standard applies to a total enclosure only (not individual panels) and is specifically geared to freestanding enclosures with internal volumes less than 2 m3 (with conditional provisions for larger volumes when using the actual sound source). Results are expressed as reductions in sound power level or sound pressure level, including A-weighted and single-number ratings.

Key Topics

Scope and applicability
- Laboratory methods for small machine enclosures (total enclosure only).
- Not intended for individual panels, close-fitting covers or cabins.
- Preferred for freestanding enclosures; special notes for enclosures fixed to machines.
Measurement methods
- Actual sound source method - uses the machine/noise source for which the enclosure is designed (preferred when practicable).
- Reciprocity method - uses an external diffuse sound field to infer insulation (applicable for volumes
