characteristic of highness or lowness of a sound is called The frequency of a sound wave determines the pitch of the sound you hear.

This calculator will compute the predicted maximum sound pressure level (loudness) at the listening position. 1. The speaker sensitivity, typically expressed in decibels (dB) with 1 watt (or 2.83 volts across an 8 ohm speaker) measured on-axis one meter away. Typical values are 85-89 dB for bookshelf speakers, 87 to 92 dB for floorstanding models, with high efficiency speakers in the 93 to 100+ dB range.
