It is considered safe for human hearing and there is no recommendation for limiting your exposure to this dB level if you are an adult. Or the level of a heat pump outdoor unit. It’s about the average level of a conversation between two people speaking in a normal voice. 60 DecibelsĦ0 decibels is a moderate noise level. It is a safe level for human hearing and sustained exposure to this noise level is not considered harmful.Ĭompared to 55 dB, 80 decibels is over 100 times more intense and over 4 times louder. 55 Decibelsĥ5 decibels is an average noise level, comparable to the noise level of a moderately quiet street in a residential neighborhood or a fairly quiet room. If you compare it to the level of a normal conversation that is at about 60 dB, 80 dB is 100 times more intense and 4 times as loud. So, while you may think that a 5 or 10-decibel difference is small, in fact, it is quite significant.Įach time a sound increases by 10 decibels, its intensity increases 10 times, and its perceived loudness increases 2 times.Ĭompared to other, more moderate dB levels, 80 decibels is considered fairly loud. ![]() It measures differences between 2 values progressively. In fact, many of the electronic devices we regularly use reach 60-80 dB.īecause of this, it’s a good idea to use a sound level meter or a sound level meter app to monitor the noise you are exposed to daily if you want to prevent hearing damage from sustained exposure to loud sounds. A noisy restaurant, hotel lobby, office, or public places like an airport or a train stationĪs you can see, it’s not uncommon for everyday noise sources to go up to 80 dB.Here are the most common examples of 80 dB sounds: Be it things we come across every day or activities we do regularly, there are many sounds around us that reach this decibel level. There’s no better way to understand how loud 80 dB is than to take examples from everyday life. Being loud, it is a noise level that may harm your hearing if you are exposed to it for longer periods (more than 8-10 hours/day). It’s equivalent to the noise of a busy downtown street. How Loud Is 80 Decibels: Examples of the Sound in Everyday LifeĨ0 decibels is fairly loud. It runs from 0 dB (the threshold of hearing) up to 130 dB (the threshold of pain that can cause instant hearing loss).Ĩ0 decibels is a moderately high noise level, close to the limit of 85 dB considered by official organizations like NIOSH (National Institute for Occupational Safety and Health) and OSHA (Occupational Safety and Health Administration) to be the maximum TWA (time-weighted average) limit humans should be exposed to for periods exceeding 8 hours/day.Įxposure to noise levels above 85 dB is considered harmful for human hearing and hearing protection is recommended whenever sound levels exceed this limit. The decibel scale is used for measuring sounds that are hearable to the human ear. In this article, we’re taking a closer look at how loud is 80 decibels, and examples of this noise level to understand if exposure to 80 dB is safe for our hearing or not. How Far Away Can This Sound Level Be Heard?īecause the decibel scale can sometimes be confusing, understanding different levels of noise is easier when we look at everyday sounds.How Loud Is 80 Decibels: Examples of the Sound in Everyday Life.The decibel scale is the name for this scale. So, rather than utilising a linear scale, a logarithmic scale with 10 as the base is utilised to depict sound levels in more comprehensible quantities. When you use a sound level metre to measure noise levels, you use decibel units (dB) to quantify the strength of the noise. SPL = 20log(P/Pref) is a formula for calculating sound pressure level. What is the formula for calculating sound pressure level? The sound intensity drops by 6 decibels (dB) with every doubling of distance.ĥ. ![]() How much do decibels decrease with distance? And 40 decibels is 1,000 decibels louder than ten decibels.Ĥ. The noise level in a quiet bedroom is 30 decibels, which is 100 decibels louder than 10 decibels. Watts Per Meter Squared (W/m^2) is the unit of sound intensity level.Ī sound with a decibel level of 20 is ten times louder than one with a decibel level of 10. What are the Sound Intensity Level units?
