Therefore, frequencies that are too low for the human ear are filtered out. There are three common filters of measuring a decibel, dB(A), dB(B), and dB(C).Ī-weighted is the standard weighting of audible frequencies which are designed to mimic the response of a human ear. In other words, it’s a unit used to measure the intensity of sound. To find this out we must learn how sound is measured.Īccording to Wikipedia a decibel is a logarithmic unit used to express the ratio of two values of a physical quantity, often power or intensity. I wondered if the sound levels could be damaging to people’s ears and how long could someone listen to music at this level before this damage would happen. It’s surprising to me how accurate these little apps actually are. Of course I took out my iPhone that has a decibel reader and measured it to be around 103 dB with peaks around 106-108 dB.
As I was sitting there I realized how loud it was in the arena and I began to wonder how loud it really was. As a church A/V/L person I was mesmerized by the lights, overtaken by the visual effects displayed on the projection screens and in love with the quality of the sound and how the bass hit you in the chest.
We sat on the floor level about midway between the back of the arena and the stage. The event had praise and worship artists, Elevation Worship, Jesus Culture and Martin Smith, Kari Jobe and Hillsong Worship with speaker Brian Houston pastor of Hillsong Church. Last night I had the privilege of attending the Outcry Tour at the Van Andel Arena in Grand Rapids Michigan.
