highSPL
highSPL is a term used to describe conditions or equipment capable of producing or tolerating high sound pressure levels, typically expressed in decibels relative to the reference pressure of 20 micropascals. In practice, highSPL is associated with environments such as live music venues and with loudspeakers and measurement setups designed to deliver or withstand substantial acoustic output, often reaching or exceeding 100 dB SPL at the source and remaining loud at a distance.
Sound pressure level is measured in decibels (dB), with the scale being logarithmic. The measurement can be
Applications of highSPL include live event reinforcement, stadium and outdoor concerts, film and television production, automotive
Safety and health considerations are central to highSPL discussions. Prolonged exposure to high sound pressure levels
