What are Accelerometers?

Time weighting is a measurement setting used in sound level meters to determine how quickly the instrument responds to changes in noise levels. By applying different response times, time weighting helps ensure noise measurements accurately reflect fluctuating or steady sound environments.

In this video, we explain:

• What time weighting is and why it matters
• The differences between Fast, Slow, and Impulse time weightings
• How time weighting affects noise measurements and reporting
• When to use each setting for environmental, occupational, and industrial noise assessments

If you’re involved in noise monitoring, environmental assessment, or acoustic consultancy, understanding time weighting is essential for collecting accurate and meaningful sound data.
