Check the sound level history of an event against limit and guide values, estimate the noise exposure of staff and roughly check the stability of ground-stacked loudspeakers. Flown or suspended systems are outside the scope of this tool.
1 · Sound level history in the audience area
Take values from a calibrated measurement; sections in chronological order.
Assessment audience
2 · Noise exposure of staff
In practice the effective attenuation is below the nominal value (SNR) of the hearing protection; use a value based on the manufacturer's data and the workplace assessment.
Assessment staff
3 · Stability of a loudspeaker stack
Assessment stack
The result is a rough estimate for level, load-bearing ground and static load. It does not replace an assessment by a competent person on site.
