What does 52 dB sound like?
Every sound has a decibel level associated with it.
If an item is 52 dB(A), then it has a sound similar in intensity to a electric fan, hair dryer, a running refrigerator and a quiet street.
Other common sounds include a blender at 90 dB(A), diesel truck 100 dB(A) and a crying baby can reach 110 dB(A)..
How loud is 68db noise level?
How loud is 68db noise level? A normal conversation is 60 – 70 db. So 68 db is a normal conversation level. A safe or acceptable noise level for constant exposure is 68 db or below.
Is 100db loud?
At 85 decibels, the maximum recommended exposure time is 8 hours. But by 100 decibels, the exposure limit drops to 15 minutes, and at 10 decibels more (110 dB), the exposure time plummets to just one minute. Exposure to sounds any longer than that could result in permanent hearing loss.
Can a sperm whale kill you with sound?
Sperm whales are so loud that their clicks are capable of killing a human within their vicinity, says one science and adventure journalist. … “These clicks are so powerful in the water that they can blow out your eardrums easily, and they can actually vibrate a human body to death,” he said.

Can frequency kill viruses?
“If the shell can be compromised [by mechanical vibrations], the virus can be inactivated.” Recent experimental evidence has shown that laser pulses tuned to the right frequency can kill certain viruses. However, locating these so-called resonant frequencies is a bit of trial and error.
