What Is 120 Db Equivalent To?

When it comes to measuring sound, decibels are the unit of choice. Decibel (dB) is a logarithmic unit that measures the level of sound in relation to a reference level. It is used to quantify the intensity of sound waves, including the loudness of sound. In other words, the higher the decibel level, the louder the sound.

If you have ever wondered what 120 decibels (dB) sound like, it should be noted that while it may seem like a small increase in decibels, it actually represents a significant increase in loudness. 120 dB is equivalent to the sound level of a chainsaw or a thunderclap, which is much louder than everyday sounds like a conversation or a car passing by.

It is important to note that prolonged exposure to sounds above 85 dB can cause hearing damage. Sounds at or above 120 dB can cause instantaneous hearing loss, and should always be avoided without proper hearing protection.

To put 120 dB into perspective, let’s compare it to some other everyday sounds:

  • 20 dB – Whispering
  • 50 dB – Normal conversation
  • 80 dB – Heavy traffic noise
  • 100 dB – MP3 player at maximum volume
  • 130 dB – Maximum output of a typical car stereo system
  • 140 dB – Gunshot or jet engine takeoff

As you can see, 120 dB is on the higher end of the sound spectrum and should be taken seriously. It is important to protect your hearing by wearing earplugs or earmuffs when exposed to high levels of noise.

In conclusion, 120 dB is equivalent to the sound level of a chainsaw or thunderclap, which is much louder than everyday sounds. Exposure to sounds above 85 dB can cause hearing damage, and sounds at or above 120 dB can cause instantaneous hearing loss. Always protect your hearing by wearing earplugs or earmuffs in loud environments.
