SIST EN 50332-2:2014 Overview

SIST EN 50332-2:2014 is a European standard developed by the CLC (European Committee for Electrotechnical Standardization) that focuses on the safety and measurement methodology of sound system equipment, specifically headphones and earphones used with personal music players. This document is Part 2 of the series and addresses the measurement of maximum sound pressure levels when headphones and personal music players are sold separately or as a package with standardized connectors allowing the combination of components from different manufacturers or designs.

The core aim of SIST EN 50332-2:2014 is to establish a reliable methodology for measuring and defining matching values between players and headphones to prevent hearing impairment due to excessive sound pressure levels (SPL). This standard complements Part 1 of EN 50332, which covers "one-package equipment" sets.

Key Topics Covered

  • Measurement Methodology for SPL Matching
    This standard specifies methods for measuring the matching values between personal music players and headphones/earphones when combined, especially when these devices have standardized connectors.

  • Player Characteristics and Testing
    Defines how to measure the maximum output voltage of a personal music player under standardized conditions including input signals, operating conditions, and analogue/digital audio output methods.

  • Headphone/Earphone Measurement
    Specifies the use of Head and Torso Simulator (HATS) for acoustical measurements and outlines the procedure to ensure proper fit and accurate measurement of sound pressure levels to maximize safety.

  • Standardized Connectors and Combination Safety
    Addresses how headphones and players can be safely paired when sold separately yet combined through standardized connectors, ensuring that SPL does not exceed safe limits.

  • Simulated Programme Signal and Input Voltage
    Uses simulated programme signal characteristic voltage, a standardized input voltage, to replicate real-world listening conditions during tests.

  • Reference to Hearing Protection Standards
    SIST EN 50332-2:2014 is harmonized with other safety standards such as EN 60950-1 and EN 60065, ensuring comprehensive protection against excessive sound pressure from audio devices.

Applications

  • Manufacturers of Personal Music Players and Headphones
    Applying EN 50332-2 helps in designing, testing, and certifying headphones and players to ensure user safety when these products are combined.

  • Quality Control and Compliance Testing
    Enables manufacturers and testing laboratories to verify that paired devices conform to safety limits on sound pressure, preventing potential hearing damage.

  • Product Development for Interoperable Audio Equipment
    Supports creation of modular audio systems with interchangeable components from different brands or designs while maintaining acoustic safety.

  • Consumer Safety and Regulatory Compliance
    Helps retailers and importers ensure that personal audio equipment meets European regulatory requirements for auditory health protection.

Related Standards

  • EN 50332-1:2013 – Defines maximum sound pressure level measurement methodology for "one-package" headphone and personal music player equipment.

  • EN 60268-7:2011 – Details headphone and earphone specifications relevant to electroacoustics.

  • EN 60950-1:2006/A12:2011 and EN 60065:2002/A12:2011 – Provide general requirements for protection against excessive sound pressure from audio devices.

  • EN 61672-1 – Defines specifications for sound level meters used during acoustic measurements.

  • EN 61260 – Relates to octave-band and fractional-octave-band filters critical for analyzing sound signals.

Practical Value

Implementing SIST EN 50332-2:2014 enables the safe integration of audio components, ensuring personal music players and headphones deliver sound within safe pressure levels. This standard is essential for manufacturers and testing facilities to prevent hearing damage risks when customers mix and match headphones and players from different sources. It supports the evolving trend toward modular consumer audio equipment while maintaining consistent hearing protection standards. By adhering to this standard, companies not only comply with European safety laws but also promote responsible product design prioritizing user auditory health.

EN 50332-2:2003:
- deletion of limits;
- addition of digital signals;
- adaptations to use the term "personal music players".
EN 50332, Sound system equipment: Headphones and earphones associated with personal music
players  Maximum sound pressure level measurement methodology, is composed with the following
parts:
− Part 1: General method for "one package equipment";
− Part 2: Matching of sets with headphones if either or both are offered separately, or are offered as
one package equipment but with standardised connectors between the two allowing to combine
components of different manufacturers or different design.
The Part 1 of this standard describes conditions and procedures for combination of player units and
headphones sold as “one-package sets”. The sound pressure limitation (SPL) of these sets is lost
when players or headphones with standardised sockets and plugs are arbitrarily combined.
This Part 2 provides measurement methods for the matching values which guarantee the SPL limit
also for the aforementioned condition.

1 Scope
This Part 2 of EN 50332 specifies methods of measuring the matching values for the use of personal
music players and headphones/earphones defined for the use with those and with standardised
connectors or interfaces allowing to combine components of different manufacturers or different
design sold separately in order to avoid possible hearing impairment by excessive sound pressure
resulting from them.
Compared with “one-package sets“ the sound pressure level at the ear cannot be fixed by only one
condition but needs at least two characteristics, one each for player and the headphones/earphones,
defined by the matching values for their connection.
Requirements for protection against excessive sound pressure from personal music players are given
