WebIn general, if you keep EVERYTHING ELSE the same, the speed of sound in a gas (like air) is slower when the density is high, and faster when the density is low. But more commonly, what we measure about air is the temperature, and the speed of sound is faster in hot air and slower in cold air. Web• Sound pressure is measured in decibels (dB) on a log 10 scale relative to a reference level • dB = 20 log 10 P 1 /P r where P r is a reference pressure level • A common reference pressure level is the threshold of human hearing at 1 kHz, referred to as sound pressure level (SPL) • A sound with twice the SPL is 6 dB louder city lights lounge in chicago
