Sorry! I read the wrong volume! RFH is actually 21,960. This gives critical distance ~ 7 meters. (not that this changes my basic point but just for the record) Robert On Wed, 22 May 2013, Robert Greene wrote: No. But the fact that a hall sounds anechoic or nearly so does not mean it is! To

Even dead concert halls in the relative sense have a lot of reverberation. A really dead hall still has a 1 second reverberation time say and most of what you hear in the audience is still reverberant sound. Robert On Mon, 20 May 2013, David Pickett wrote: At 00:50 18-05-13, Robert Greene

I believe Gilbert Briggs of Wharfedale did something like this in the 1950s. He hired major concert halls and other public venues in the UK and USA to give concerts comparing live with recorded sound. Of course, the purpose was to promote his Wharfedale loudspeakers and Quad amplifiers (he and
