The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device produces high recognizable frequencies and if it adjustments to the signal while at it. 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.
