What is Sound Calibration?
Sound Calibration is the process of verifying and adjusting sound measuring or emitting equipment to ensure accurate sound pressure level (SPL) readings or output. This includes devices like sound level meters, microphones, audiometers, and speaker systems. The goal is to ensure that audio measurements and playback meet precise standards for accuracy, safety, and compliance.
Why is Sound Calibration Important?
Sound Calibration is crucial in industries such as environmental monitoring, occupational health and safety, audio engineering, telecommunications, and medical diagnostics. It ensures that noise levels are measured correctly, hearing tests are accurate, and sound systems perform optimally.
- Ensures precise and reliable audio measurements
- Compliance with standards such as ISO 17025, IEC 61672, and OSHA
- Protects hearing and workplace safety
- Optimises audio system performance in studios and public spaces
- Supports accurate environmental noise assessments
What Equipment Needs Sound Calibration?
Sound Calibration is needed across a wide variety of instruments, such as:
- Sound Level Meters
Audiometers
- Studio Microphones and Audio Analysers
- PA Systems and Speaker Installations
- Environmental and Occupational Noise Monitoring Equipment
Who Needs Sound Calibration?
Sound calibration is essential for organisations and professionals involved in noise monitoring, control, or compliance, including:
- Environmental consultants and acoustic engineers
- Occupational health and safety officers
- Construction and civil engineering firms
- Manufacturing and industrial workplaces
- Healthcare and audiology clinics
- Event venues and entertainment companies
- Local authorities and environmental monitoring agencies
- Testing and calibration laboratories
How Often Should It Be Calibrated?
- Every 12 months – Industry standard for most noise measurement equipment
- Every 6 months or before major assessments – For critical applications or legal compliance
- Before and after any major noise survey
- After instrument repair, impact, or exposure to extreme environments
Follow ISO 17025, HSE, or manufacturer guidelines for specific recommendations.
