IEC 60268-34 is an international standard that provides specifications and guidelines for the design, performance, and testing of sound systems in broadcasting, recording, and similar applications. It is part of the International Electrotechnical Commission's (IEC) series of standards for audio, video, and multimedia systems.
Scope and Purpose
The main purpose of IEC 60268-34 is to ensure the accuracy, reliability, and interoperability of audio equipment used in professional environments. It covers a wide range of audio systems including amplifiers, loudspeakers, mixers, microphones, and headphones, among others.
This standard sets forth requirements that must be met in order to achieve high-quality audio reproduction, accurate signal transmission, and minimal interference. It also includes test methods for evaluating the performance of these systems, allowing manufacturers to verify compliance with the standard.
Key Specifications
IEC 60268-34 specifies various parameters that need to be considered when designing and evaluating audio systems. Some of the key specifications include:
Sensitivity: The efficiency of converting electrical signals into sound pressure level.
Impedance: The total opposition to the flow of electric current, affecting loudspeaker matching and power transfer.
Frequency response: The range of frequencies over which the system can accurately reproduce sound.
Distortion: The measure of unwanted changes in the waveform, indicating the quality of audio reproduction.
Intermodulation distortion: The distortion caused by the mixing of harmonics or other undesired frequency components.
Noise: The unwanted sound generated by the system, including hiss, hum, or other background noise.
Crosstalk: The unwanted transfer of signals between different audio channels.
Conclusion
In conclusion, IEC 60268-34 is an important standard in the field of professional audio systems. It ensures that audio equipment meets specific requirements for accurate sound reproduction, reliable performance, and compatibility with other devices. By adhering to this standard, manufacturers can provide high-quality audio solutions that meet the needs of various applications, from broadcasting to recording studios and beyond.
