What is the audible range can we hear sound waves having frequency of about 100 000 Hz?
Other animals have hearing ranges different from that of humans. Dogs can hear sounds as high as 30,000 Hz, whereas bats and dolphins can hear up to 100,000-Hz sounds….Learning Objectives.

Is it safe to listen to binaural beats?
“Binaural beats may be good for meditation and relaxing, but that is probably all they are good for,” Segil says. “It’s challenging to say listening to these tones is going to cause a person’s brain waves, as measured on an EEG (electroencephalogram), to synchronize with the tone’s frequencies.”
What is the frequency of intelligence?
For example: Our brain uses 13Hz (high alpha or low beta) for “active” intelligence.
Can I listen to binaural beats while sleeping?
The soothing nature of the sounds may be what really helps, but that’s fine if you just want to relax and drift off to sleep. You can also find quite a few apps that generate binaural beats at your phone’s app store. If you want to relax and sleep just be sure to set the frequency in the theta range (4 – 7 Hz).
Which brainwave is best for sleeping?
All the way at the bottom of the spectrum of brain waves — below theta waves — are the low, deep, slow delta waves. Both delta waves and theta waves occur when you’re asleep, but delta waves are the waves that dominate when you’re in a period of deep, restorative sleep. They measure in the 0.5 and 4 Hz range.
Can binaural beats help depression?
Our study results showed that the depression level was significantly decreased after listening to 30-minute familiar music with alpha binaural beats in the afternoon daily for five days. We also found that there was a negative correlation between relaxation and depression.
