In addition to the other uses cited elsewhere, so-called RF
microphone carrier systems are used for instrumentation purposes
notably where extremely low frequency reponse is required.
I remember the big Sennheiser Brochure mentioning that MKH106's were
available in version with a lower response limit of 1 or 0.1 Hz on special
order.
Referring again to Bruel & Kjaer, their microphone carrier
system with an appropriate capsule is capable of measuring
down to frrequencies approaching DC (i.e., it can act like an
electronic baramoeter), while still maintaining response up to
150 kHz. Used with something like a B&K 4147 capsule, you have
an acoustica measuring system with response from under 0.01 Hz
to over 20 kHz within a 2 dB envelope.
Ahem, yes, they like their transducerspecs to meet or exceed exceed normal
semiconductor circuit specs ... O;-)
Kind regards
