Abstract
An audio ramping technique (200) reduces acoustic shock in radio (100) that has multiple operating modes each having a different nominal audio speaker level. The ramping technique (200) sets the audio speaker level to the same initial sound pressure level (SPL) (208) regardless of the mode of radio operation and then ramps the audio level (216) until either a user initiated control signal (212) is received or the audio level reaches a maximum threshold level (210).
