Nov 23, 2024 · High-frequency (≥15.000Hz) sounds are higher-pitched (short wavelength) than low-frequency (long wavelengths; ≤100Hz) sounds. Frequency is measured in cycles per second. For sound, the most-commonly used unit is hertz (Hz), or cycles per second. Most humans can perceive sounds with frequencies between 30 and 20,000 Hz.
Apr 12, 2024 · Learn about image representation for your IGCSE computer science exam. This revision note includes pixels, colour depth, and resolution.
For images, the higher the bit depth, the more accurately a sound can be recorded, but the larger the file size. Typical bit depths are 16 bit and 24 bit.
Apr 1, 2018 · In the picture below is two sound waves, the lower tone (longer wave) on the left and the higher tone (shorter wave) on the right. For example, a very low deep base sound could be 30 Hz and a high or an upper treble sound could be 2.6 kHz. The average human can hear between 15 Hz to 20 kHz.
We will explore how these aspects impact file size and the accuracy of sound reproduction, and discuss the balance between sound quality and file size in different contexts, such as high-fidelity music and voice communication.
In summary, computers represent sound by capturing samples of the analog wave at a certain rate and resolution. By understanding sample rate, bit depth, and file size calculations, we can ensure high-quality digital sound or optimize file size for various uses. WHAT IS SOUND ?

Feb 2, 2016 · A sound with high amplitude pushes the sound molecules with greater force, creating the increase in loudness that you hear. For example, think about your friend drawing along with the music again. When the music is loud, his picture is very big.
