An estimated decay curve is defined using a linear regression between the SCOP and SEP points This decay curve is extended to infinity Therefore the integration between the SCOP point and infinity is possible as the surface of the triangle extended surface is known Brand of ACOEM 9 5 At the end of the process the reliable decay curves are completely defined and the RT determination is applied REVERBERATION TIME CALCULATION ACCORDING TO THE USER DEFINED PARAMETERS User defined parameters X Start dB Defines the regression starting point RSP on the decay curve to be considered for the linear regression calculation The RSP point is defined as being the point on the decay which is X decibels below the level of the SCOP The RSP point is frequency dependent Y Dynamic dB Defines the regression ending point REP The REP point is defined as being the point on the decay curve which is Y decibels below the RSP point The REP point is frequency dependent otrict The strict option disables the calculation on the band where it is not possible to define the REP point i e if the decays dynamic range is lower than Y X In this case the RT value for the corresponding band is not calculated The figure below shows the principle of the RT value calculation The Reverberation time for the corresponding frequency band is calculated as being the slope of the linear regression between the RSP and REP In the case wh
