Is there a tone generator app?
The Tone Generator app generates pure sine wave tones at frequencies from 20hz to 22,000hz. Tone generation is useful in tuning instruments, hearing tests, science experiments, and testing audio equipment. It’s a free download on the Apple App Store or Google Play store.

What is the highest Hz sound?
The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.
How high can a human hear?
Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)
How does Hertz app calculate frequency?
The SpectrumView app can be used to measure the highest tones you can sing, obtain visual feedback of the frequencies in your speech, identify an annoying sound, calibrating musical instruments, or generally for all sorts of acoustic analysis.
Whats the Hz of a human?
Human Vibration Parameter Comparison and Result Discussion. According to the existing research, the natural frequency of a human-standing body is about 7.5 Hz, and the frequency of a sitting posture in the cab is generally 4–6 Hz.
What Hz can dogs hear?
| Species | Approximate Range (Hz) |
|---|---|
| human | 64-23,000 |
| dog | 67-45,000 |
| cat | 45-64,000 |
| cow | 23-35,000 |
How many Hz Should a 15 year old hear?
The ‘normal’ hearing frequency range of a healthy young person is about 20 to 20,000Hz. Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there.
How many hertz is a human scream?
Normal speech changes in volume at a low rate – about 4 to 5 Hertz or cycles per second. Screams, however, change in volume very quickly and very widely — from 30 Hz up to 150 Hz.
