This phenomenon highlights the difference between objective signal strength and subjective hearing.

Adam Curry shares a technical history of radio broadcasting, explaining how DJs used "quick start" turntables and slip mats to queue records.

The discussion shifts to the increasing presence of mosque speakers in Amsterdam and the resulting neighborhood disputes over decibel levels and frequency of prayer calls.

Adam Curry recounts his history in pirate radio and television, admitting to creating "media magic" through faked satellite interviews with celebrities like Janet Jackson. He explains how technical tricks were used to make pre-recorded answers appear as live conversations.

A massive "Beyond Wonderland" rave held in the Oakland Coliseum parking lot generated thousands of noise complaints from residents as far as seven miles away.

Adam Curry describes his early obsession with radio, including building a pirate transmitter in Amsterdam and practicing his broadcasting voice for hours as a teenager. He recounts working at a hospital radio station and later adopting the persona "John Holden" on Radio Decibel.
