There go the laws of physics again !! p=Sd*Xmax*f^2*pi*rho0/(r*sqrt(2)) where p=sound pressure in Pa, Sd=eqv. piston area in m2, Xmax=max peak excursion in m, f=frequency in Hz, rho0=1.2kg/m3, r=speaker-to-mic distance in m. or in excel form http://www.linkwitzlab.com/spl_max1.xls *Players:* SliMP3,Squeezebox3 x3,Receiver,SqueezePlayer,PiCorePlayer x3,Wandboard *Server:* LMS Version: 7.9.0 - 1453293926 on Centos 7 VM on ESXi 6 on HP N54L *Plugins:* AutoRescan/BBCiPlayer/PowerSave/PowerSwitchIII/Squeezecloud *Remotes:* iPeng8/Orangesqueeze/PC/Jivelite *Music:* 383GB,1269 albums 17756 songs 4381 artists mostly FLACs *Want a webapp ?* See http://forums.slimdevices.com/showthread.php?104305-Webapp-for-LMS ------------------------------------------------------------------------ Jeff07971's Profile: http://forums.slimdevices.com/member.php?userid=49290 View this thread: http://forums.slimdevices.com/showthread.php?t=105563 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
