1. What is Pure Tone Generation?

Pure tone generation involves creating a sinusoidal audio signal with a specific frequency, amplitude, and duration. Pure tones are fundamental in audio testing, hearing assessments, and sound synthesis applications.

2. How Does the Calculator Work?

The calculator generates pure tone parameters using the formula:

Where:

• \( y(t) \) — Audio signal amplitude at time t
• \( A \) — Amplitude (0 to 1)
• \( f \) — Frequency in Hertz (Hz)
• \( t \) — Time in seconds

Explanation: The equation generates a sine wave with the specified frequency and amplitude over the given duration.

3. Importance of Pure Tone Parameters

Details: Accurate tone generation is crucial for audio testing, hearing assessments, calibration of audio equipment, and various scientific and medical applications.

4. Using the Calculator

Tips: Enter frequency in Hz (20-20000 for human hearing range), duration in seconds, and amplitude between 0 and 1. All values must be positive and within valid ranges.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical frequency range for human hearing?
A: The average human can hear frequencies from about 20 Hz to 20,000 Hz, though this range decreases with age.

Q2: What does amplitude represent in audio signals?
A: Amplitude represents the loudness or intensity of the sound, with 0 being silent and 1 being maximum amplitude.

Q3: Why use a sample rate of 44.1 kHz?
A: 44.1 kHz is the standard CD quality sample rate, which can accurately represent frequencies up to 22.05 kHz according to the Nyquist theorem.

Q4: Can I generate multiple tones simultaneously?
A: This calculator generates parameters for a single pure tone. Multiple tones would require more complex synthesis techniques.

Q5: What applications use pure tones?
A: Pure tones are used in audiometry, audio equipment testing, scientific research, music synthesis, and various diagnostic applications.
