JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device generates low frequencies that can be heard, and if it alters the signal on its way through. JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response tells how well an audio component makes high recognizable frequencies and if it makes any changes to the signal on its way through. The sound pressure level, is the level of pressure of sound, in decibels, dB, JBL Tune Flex's measurement is 108dB/mW.
Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
