Abstract:
1. An acoustical estimation device for obtaining an estimation of an acoustical output of at least one loudspeaker, wherein said at least one loudspeaker is connected to at least one electronic audio device having an electronic output, said acoustical estimation device comprises an analog-to-digital converter and a microcontroller that sample said electronic output of said at least one electronic audio device, and said estimation of said acoustical output of said at least one loudspeaker is processed to determine an estimated noise dosage arising from said acoustical output of said at least one loudspeaker, and is obtained from said sampled electronic output of said at least one electronic audio device, and using a transfer function that relates said acoustical output of said at least one loudspeaker and said sampled electronic output of said at least one electronic audio device.
