Certified Technology Specialist Exam Practice 2026 – Complete Preparation Guide

In audio systems, the frequency of sound waves is measured in hertz (Hz). Hertz represents the number of cycles per second of a sound wave. This frequency measurement is crucial for understanding audio quality and characteristics, such as pitch. Higher frequencies correspond to higher pitches, while lower frequencies relate to lower pitches. For instance, a sound wave with a frequency of 440 Hz is recognized as the musical note A above middle C, which is commonly used as a standard tuning reference.

Measuring frequency in hertz is essential for sound design, audio engineering, and various applications within the field of audio technology, ensuring that audio signals are reproduced accurately respecting the original sound properties.
