1kHz to 24 kHz | High frequency sine wave test tone

High-frequency sine wave speaker test tone from 1 kHz to 24 kHz for an audio lover who want to test his/her sound system and hearing ability vs frequency. Each frequency duration is 3 seconds. The video contains wave pattern too.

If you use this video as hearing test tone you must use good quality headphones or hi-fi sound system because laptop loudspeaker frequency responds not good both low and high frequencies
