Piekgeluidsdrukniveau refers to the maximum instantaneous sound pressure level measured during a sound event. Unlike average sound pressure levels which provide a smoothed representation of loudness over time, the peak sound pressure level captures the highest amplitude of the sound wave. This is particularly relevant for transient sounds or impacts that produce sudden, short bursts of intense sound.

It is typically measured in decibels (dB) and is a crucial parameter in assessing potential noise hazards and their impact on hearing. For example, impulse noises, such as those from a gunshot or a hammer striking metal, can have very high peak sound pressure levels even if their overall duration is short. These high peaks can cause immediate damage to the auditory system, even if the average sound level over the same period is lower.

Regulatory bodies and safety standards often specify limits for peak sound pressure levels to protect workers and the public from hearing loss and other adverse health effects. Measuring peak sound pressure level requires specialized equipment capable of responding very quickly to rapid changes in sound pressure. Understanding the difference between peak and average sound pressure levels is essential for accurate noise assessment and control.
