주파수 사운드 구성기 지정

1. This tool can generate sounds at specified frequencies and allow you to download them locally.

2. Introduction to waveforms:

(1) Sine wave: A pure, single-frequency sound commonly used for testing and as a fundamental tone in music.

(2) Square Wave: A sound rich in harmonics, commonly used in electronic music and retro game sound effects.

(3) Sawtooth Wave: A bright and aggressive sound, commonly used in synthesizer effects.

(4) Triangle Wave: A soft sound with more harmonics than a sine wave but fewer than a square wave.

3. Introduction to Sounds in Different Frequency Bands

(1) 20Hz ~ 200Hz: Low-frequency tones, such as bass.

(2) 200Hz ~ 2,000Hz: The pitch of musical instruments and the frequency range of most human speech.

(3) 2,000Hz ~ 20,000Hz: Sharp high-pitched sounds, the sounds of many birds and small mammals, and ultrasound.

4. Note: The normal human ear can hear sound frequencies ranging from 20Hz to 20,000Hz; however, the range of audible frequencies varies depending on an individual’s physiological age.

5. Note: Do not wear headphones while testing the sound!
