MUIC & ACOUTIC – OUND PHYIC & PYCHOACOUTIC CALCULATOR
Pitch Perception Frequency
A precise tool.
What is the Pitch Perception Frequency & How does it work?
The Mel scale is a perceptual scale of pitches that relates to how humans perceive pitch. It was developed by Alexander Graham Bell and is based on the human auditory system’s response to frequencies.
text{Mel}(f) = 2595 log_{10}left(1 + frac{f}{700}right)
f = frequency in Hz
This formula helps convert frequencies from the linear scale to the Mel scale, which is more aligned with human perception of pitch.

Frequently Asked Questions
What is the Mel scale?
The Mel scale is a perceptual scale of pitches that aligns with human auditory perception, developed by Alexander Graham Bell.
How do I convert Hz to Mel?
Use the formula: Mel(f) = 2595 log10(1 + f/700), where f is the frequency in Hz.
Why use the Mel scale instead of Hz?
The Mel scale better represents how humans perceive pitch, making it useful in audio processing and music applications.
Can you give an example of converting a frequency to Mel?
Sure! For 1000 Hz: Mel(1000) = 2595 log10(1 + 1000/700) ≈ 2513.24 Mel.
What is the range of frequencies typically used in the Mel scale?
The Mel scale covers a wide range, but it's most useful for frequencies between 20 Hz and 8000 Hz, which are audible to humans.
How does the Mel scale relate to music theory?
While not directly tied to traditional music theory, the Mel scale is crucial in digital signal processing for tasks like speech recognition and music information retrieval.
Is there a reverse formula to convert Mel back to Hz?
Yes, the reverse formula is: f = 700 * (10^(Mel/2595) - 1).
