Psychoacoustic analysis reveals that sound pressure level is a less than ideal predictor of human reception of noise, so efforts have been made since the 1960s [6] [7] to apply loudness metrics instead, which can incorporate other factors such as spectral and temporal auditory masking and level-dependent frequency weighting to more accurately ...

Sometimes, people need to find a place to vent, so they go online to share photos of the things that their wives and girlfriends do that are irritating yet also endearing.
