2 Audio Tone generators Videos
Basic and Advance types
20 Hz to 20 kHz
Can be used to Check amplifier signal path, Studio engineer
Good Morning Hearing Check Up, or find tinnitus frequency (if any) or Just for Fun for the Studio Engineers.
Warning - Important
Take care of your ears - Always listening at a low volume!
These Soundcheck videos is a technical instrument - These "Tone generator" can´t replace a medical hearing test.
Basic generator
An easy way to do a frequency check for amplifiers, signal path, speakers etc. 4 test modes. 40Hz to 15 kHz in 19 steps.
4 Output modes:
1. Simultaneously Left & Right
2. Switches between Left and Right
3. White noise, simultaneously Left & Right
4. White noise, switches Left & Right
Technical information:
An easy way to do a frequency check for amplifiers, signal path, speakers etc.
Frequency range: 40Hz to 15kHz in 19 steps 40, 75, 150, 440Hz, 1, 2,....15kHz
Output modes: L & R, L, R, and White noise check
Audio recorded at -20dB, 44,1 kbit
Note! Output level out is not weighted to compensate the ear frequency response, there for frequency in region approx 1kHz - 2kHz appers perceived as stronger compare to other frequency especially bass tones.
Warning - Important
The Soundcheck is a technical instrument - "Tone generator" and can´t replace a medical hearing test.
Note! Speakers in small portable units often fail to reproduce frequencies above 5000 Hz, and the speaker(s) can also generate parasite (false) frequencies.
Take care of your ears - Always listening at a low volume!
