DECIBEL LOUDNESS COMPARISON CHART Here are some interesting numbers collected from a variety of sources that help one to understand the volume levels of various sources Decibel Symbol dB is a logarithmic unit that indicates ratio or gain Decibel is used to indicate the level of acoustic waves and electronic signals The logarithmic scale can describe very big
Sound levels are most commonly measured in decibels dB which range from barely audible to loud enough to cause physical pain The risk of hearing loss starts at around 70 dB Exposure to sounds at 85 decibel When comparing sound levels of different noises and their potential for causing hearing damage A weighted decibels dBA are often used instead of dB The main difference is that the dBA measurement takes into account

Check out our noise level chart and corresponding reduction in actual sound pressure level as well as perceived volume See the full noise db chart here Comparing Noise Criterion NC NCB RNC to Noise Rating NR and dB A Noise Criterion NC were established in U S for rating indoor noise noise from air conditioning equipment
For example a sound that is 10 times more powerful than 0 dB near silence is 10 dB while a sound that is 100 times more powerful would be 20 dB Most industrial products if given a Decibels dB are a way to measure how loud or quiet a sound is on the decibel scale This scale helps us compare sounds from whispers around 20 dB to normal conversations about 60
