Overview

IEC TR 61305-6:2005 provides recommended procedures for subjective listening tests on loudspeakers intended for home use. It complements objective measurements (e.g., IEC 60268-5) by defining how to conduct and evaluate listening tests so that sound characteristics of different loudspeakers can be compared reproducibly. The report focuses on two validated test formats: single stimulus ratings and paired comparisons and is applicable to stereo and multichannel systems.

Key topics and technical requirements

Scope and purpose

Applies to loudspeakers conforming to IEC 61305-5 and intended for domestic listening.
Designed to establish standard comparison methods for perceived sound quality.

Listening room and acoustics

Typical room volume: 80 m³ ± 20 m³, room height 2.75 m ± 0.25 m; rectangular plan (side ratio ≤ 2:1).
Reverberation time requirements with stability across octaves (measurement per ISO 3382); RT must not vary more than +25 % / −20 % within 400 Hz–8 kHz.
Background noise (A-weighted) limited to ≤ 25 dB AFm.

Loudspeaker placement and masking

Loudspeakers hidden behind an acoustically transparent screen to prevent visual bias.
Typical placement: manufacturer-recommended positions, at least 0.5 m from walls; stereo angle such that each listener’s angle is ≥ 45°.

Electrical and level requirements

Use a source, level control and a power amplifier with low output impedance and sufficient power (no clipping).
Tone controls set flat; system deviations limited to ±0.5 dB from 20 Hz to 20 kHz (measured at system input and amplifier output).
Level setting: pink noise with A-weighted level ≈ 75 dB as practical reference.

Test procedures and analysis

Detailed protocols for single stimulus ratings (absolute scoring) and paired comparisons (relative ranking).
Guidance on programme material, listener selection and number, test duration, questionnaires, statistical evaluation (variance analysis, factor analysis, reliability).

Applications and users

Who uses it:

Loudspeaker manufacturers (R&D, QA), independent test laboratories, audio reviewers, certification bodies.

Practical applications:

Product development and tuning based on perceptual feedback.
Comparative bench-marking of consumer loudspeakers.
Formal listening test design for reviews and conformance reporting.
Multichannel/surround listening evaluations (procedures scale to multiple channels).
