The Fletcher-Munson curves apply to soundfield levels heard by an average
listener in the listening environment. That is more a function of the
listener's audio system and its settings than to the peak/average modulation
of an AM or FM transmitter.
The F-M curves show that even the "loudest" AM/FM transmission will be peaky
in the mid-range at SPLs from the receiver/sound system of ~90 dBa and
less -- and ultimately that SPL is controlled by the listener.
