WebThe Decibel Scale. You may have noticed that when people talk about the loudness of a sound, they describe it in units of decibels rather than watts per meter squared. While sound intensity (in W/m 2) is the SI unit, the sound intensity level in decibels (dB) is more relevant for how humans perceive sounds. The way our ears perceive sound can be more … WebThe tympanic membrane can actually tolerate fairly high pressures, but do reach a level where the amount of pressure can no longer be tolerated. The eardrum may rupture at pressures above 35,000 pascals (35 kPa, or 5.08 psi) but is normally at higher levels, closer to 100,000 pascals (100 kPa or 14.5 psi). Ear Drum Rupture Expectations Water
