Table A.2.

Calculated psychoacoustic characteristic values for 32 time sections with a duration of 3 s based on a run-out measurement over a period of 10 min under controlled operating condition A7W55. The calculations are based on the recorded sound pressure levels Leq at measurement position 14, Qh is the part load heating capacity at A7W55 in %, nc is the speed of the compressor in rpm, LWA is the sound power level of the heat pump demonstrator in dB(A), N is the loudness in sone, S is the sharpness in acum, T is the tonality in tuHMS, R is the roughness in asper, and F is the fluctuation strength in vacil.
