PARAM, ACPREFDB

Bulk Data Entry Specifies the reference acoustic power value used to calculate Acoustic Power (ACPOWER) in decibels (dB).

Parameter Values Description
ACPREFDB Real > 0.0

Default = 1.0

The Acoustic Power (ACPOWER) in decibels can be calculated using the following equation:
A C P O W E R ( d b ) = 10 * log 10 A C P O W E R A C P R E F D B MathType@MTEF@5@5@+= feaahqart1ev3aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq=Jc9 vqaqpepm0xbba9pwe9Q8fs0=yqaqpepae9pg0FirpepeKkFr0xfr=x fr=xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaamyqaiaado eacaWGqbGaam4taiaadEfacaWGfbGaamOuaiaaygW7caGGOaGaamiz aiaadkgacaGGPaGaeyypa0JaaGymaiaaicdacaGGQaGaciiBaiaac+ gacaGGNbWaaSbaaSqaaiaaigdacaaIWaaabeaakmaabmaabaWaaSaa aeaacaWGbbGaam4qaiaadcfacaWGpbGaam4vaiaadweacaWGsbaaba GaamyqaiaadoeacaWGqbGaamOuaiaadweacaWGgbGaamiraiaadkea aaaacaGLOaGaayzkaaaaaa@55AA@
