Conclusions
§The sine sweep method revealed to be
systematically superior
to the MLS & TDS methods for measuring electroacoustical impulse responses
§The ESS
method also allows for measurement of not-linear devices and to assess harmonic
distortion
§Current
limitation for spatial analysis in room acoustis is due to transducers (loudspeakers and microphones)
§A new
generation of loudspeakers and microphones, made of massive arrays, is under
development.
§The “harmonic
orders” impulse responses obtained by the exponential sine sweep method can be used for not-linear convolution, which yields more
realistic auralization
