accuracy of loudspeaker measurement in anechoic chamber: dimension and absorber

[Chuping Liu <tracy_liu_99@xxxxxxxxx>]

Dear List,

When loudspeaker is measured in anechoic chamber, for valid results at low frequencies, it means large anechoic chamber and large absorbent wedges. I found quite some literature discussing the accuracy of loudspeaker measurement in terms of different wedges. Yet I haven't found any literature talking about the measurement accuracy (in terms of frequency extend and errors) regarding the physical dimensions of the anechoic chamber, or ideally for both of chamber dimensions and absorber characteristics. 

If anyone is aware of the existence of such literature, I would appreciate to be pointed out. Thanks.


Regards,
Chuping
