This audio is a straightforward, yet comprehensive sound test, performing a linear sweep from a low frequency of 10 Hertz to a high frequency of 22000 Hertz, all within a span of 3 seconds. The audio level is maintained at -3 decibels full scale, ensuring consistency throughout the audio test. The tone of the sweep is clear and piercing, adopting a chirping characteristic as it progresses through the range of frequencies. This sinusoidal wave, or 'sine' wave as it is commonly known, delivers a smooth and uninterrupted transition through the frequencies, making it an ideal tool for testing audio equipment or human hearing abilities.
