Michael Lawrence (co-host of the Signal To Noise Podcast), joins us to talk about SPL, loudness, and the audio engineer's responsibility when it comes to exposure risk at live sound events. Expressed through his work as a system engineer and senior instructor at Rational Acoustics, he brings humanity to the technical aspects and numbers when balancing a concert's perceived loudness and safety of all involved.  This episode features music by Audiologist and Talking Ears producer, Juan Vasquez and his band The Absolute Threshold.
