What is a Decibel.Decibel levels are important to you because they tell you how loud or quiet a sound is and this is very important as if something is too loud it can damage your hearing permanently. I don't intend to get into a technical description of the decibel as a measurement of sound pressure levels, if you would like a full technical description then you can find it at wikipedia.
How loud is loud?Bellow is an illustration of decibels against common sounds that most people are familiar with to try to help you understand the decibel scale.
At 85dB most people can suffer hearing damage from prolonged exposure, it is recommended that you are not exposed to 85dB for more than 8 hours in any one day.. A noise is just an unwanted sound, in some cases what you perceive as being noise others perceive as being a pleasant sound such as the differences in opinions that my daughter and I have regarding what is on the stereo!
However we also use noise to indicate that not only is a sound unwanted but that it is usually too loud.
Noise is a very real hazard in many workplaces and noise induced hearing loss is something that you have to seriously protect yourself against.
Noise Induced Hearing LossNoise induced hearing loss is what occurs if you are exposed to noise that is too loud for too long. In an industrial setting occupational health and safety regulations require the use of hearing protection if the average sound level is 85dB or more as well as a host of other requirements such as annual hearing tests to assess noise induced hearing damage.
This means that you will need to get equipment to measure the sound levels within your workplace and use hearing protection to protect your hearing and the hearing of your employees. Many people think that they don't need to use hearing protection at home, but it is just as important as using it within an industrial setting.
Having worked within press shops with 1000 ton presses in operation I would recommend the full earmuff style ear protection shown here rather than the plugs that you insert into your ears if you really want to protect your hearing. How much Noise can we Endure?Everyone's hearing is slightly different and as with many things people's endurance and ability to withstand damage vary considerably. Measuring Decibel LevelsMeasuring how loud something is can be done quite cheaply and easily with simple tools that are available today.
The decibel meters available online are not that expensive however if you are looking for one to monitor your workplace ensure that you purchase one that meets the requirements of legislation as some are very basic. If you have any doubts at all about whether your work environment is too noisy you should get a meter such as the simple one shown here and measure the noise levels. Protecting your hearing from high decibel levels.In environments where you are exposed to noise above 85dB it is advisable to wear hearing protection to prevent hearing loss. Wearing too strong a hearing protection device in lower noise environments can also cause problems as you would not be able to hear what people have to say or even shouted warnings; so wear the right hearing protection for the right environment. If you are concerned about decibel levels wear ear protection to ensure that you save your hearing.
Correctly Wearing Hearing ProtectionFar too often as a manager in noisy work environments I have found employees wearing ear protectors incorrectly. The problem is that they can still sue you if they then develop hearing loss even though they have taken it upon themselves to not use the provided protection correctly. Concerned about decibel levels?Would you use hearing protection at home if using noisy tools?

AlexanderWillox 2 years ago from UK Well written hub, perhaps worth mentioning the difference between a meter which gives a spot measurement and a dose meter.
We usually measure how loud sound is through the use of a measure called the decibel, one decibel being one tenth of a bel, a very infrequently used measure.
A doubling of your Decibel reading does not mean a doubling of the noise, for every 10dB increase in sound our perception of loudness doubles.
What most people think of as loud is anything above about 80dB which is the sound of an alarm clock. A sound is a vibration that we pick up via our eardrums; the strength of which we can measure using decibels. We use noise to describe a sound that is louder than we are comfortable with, often so uncomfortable that it could potentially cause damage to our hearing. I have worked in factories where there are hundreds of presses in operation stamping out panels for car parts; the noise in these factories is such that you feel every stroke of the big machines as well as hearing them.
Noise is a vibration and if those vibrations are too big and powerful they can cause severe damage to our eardrums; even rupture them. However the table below gives guidance at to how long someone can safely be exposed to sound levels. You can even download applications to your phone for measuring decibel levels however these would not be that accurate and should only be used for "fun". Better to measure and monitor your decibel levels than to ignore them and get hit with a lawsuit later on from an employee who has suffered hearing damage.
If you know the level of noise that you will experience then you can choose hearing protection that will reduce the sound to less than 85dB.
They push back earmuffs from their ears to leave their ears exposed or fail to fully insert plugs. It is vital that you police the use of hearing protection thoroughly as not everyone realizes or believes how easy it is to damage hearing.
We sometimes provide ear muffs and ear plugs that are too efficient for the levels of noise in our work.
If you want to implement lean manufacturing then you need to understand Lean Manufacturing Principles and Concepts. Even with quality hearing protection you can still hear and feel the noise within the factory.
You should compare the ratings of the protection that you provide against the actual decibel levels of your environment to ensure that you don't make it impossible for your operators to hear each other or even the machines. You would certainly suffer severe hearing loss if you operated these machines without protection.
