What is the permissible SPL exposure according to OSHA guidelines?

SPL, or Sound Pressure Level, is an important measure of how loud sounds are. In science, SPL is measured in Pascal (Pa), but we often use decibels (dB) for everyday use.

Why is SPL monitored?

• Quality: optimal SPL ensures clear music without discomfort.

• Regulations: noise limits for clubs are set by laws in some countries.

• Hearing Health: SPL monitoring protects against overexposure.

• Performance consistency: maintaining uniform sound levels for all attendees.

How do you measure a representative SPL in a club or festival?

• SPL is measured at ear level, ideally positioned in the crowd to capture the average attendee experience.

How do you measure the SPL of a speaker?

• SPL of a speaker is measured at a standardized distance of 1 meter.
