20000hz adults cant hear
I have skimmed your page on HD audio. Elephants can hear and make sounds well below human range, to as low as 14 to 16 hertz. This test helps you benchmark the highest boundary of your system's frequency extension. I read this article in an attempt to discover how I can measure the decibel output of ultrasonic devices accurately above 25kHz, and though I can see the tools you used, I am wondering if you could shed light on how I would go about accurately measuring these high frequency tones, thanks. When I do this in my office my dog at higher frequencies starts looking aound searching for vermin.
The World Beyond 20kHz
The metal-dome tweeters had an irregular picket fence of peaks and valleys in their amplitude response above 20kHz. June 30, at am. May 27, at am. The information from the outer hair cells, which seems to be more related to waveform than frequency, is certainly correlated with the frequency domain and other information in the brain to produce the auditory sense. Unlike low frequencies, high frequencies are easily reproduced through smaller and cheaper speakers. Jaahda Jinnah says:.

Babies have a different way of hearing the world by listening to all frequencies simultaneously
Dan O says:. Distortion and transient intermodulation should be held to a few parts per million in each amplification stage, especially in systems with many amplifiers in each chain. Lawrence Gulick, George A.
We are certainly pushing the envelope. I suspect that truly excellent sound, perhaps even perceptual perfection? This is thanks to a high end mic preamp and audio repair software.
