The Importance Of Environmental Testing For Noise

These days there is more and more focus being put on our environment, and one focus on particular is nuisance noise, which can take the form of both domestic noise and industrial noise.

But setting domestic noise aside, as a business you will have a legal duty of care with regards to noise on a couple of fronts. Firstly if you are using mechanized equipment within your factory then you have duty of care to ensure your equipment produces noise that is acceptable for people to work around.

If the noise a machine produces is above the relevant legal limit then you will need to ensure that staff are given suitable protection against the noise in terms of using ear defenders. You will also need to ensure to use a sound level meter to accurately test the noise levels around the offending machine, as it may be that if sound levels are high, that employees that are not operating the machinery but are working in its near vicinity also need to be given suitable ear protection.

If this sounds like your factory then you would be well advised to buy a legally accurate sound level meter, as you will be required to provide ongoing noise monitoring and most often have to keep accurate records of noise levels.

The importance of regularly monitoring sound levels cannot be overstated, as in the event of a person claiming they have got industrial deafness, then the noise level records may prove (or not!) that they were within legal limits, and in such a case if you find yourself being sued for such a personal injury then accurate records could prove to be your main defense.

For many companies buying a small handheld sound level meter makes good sense, as they are cheap, accurate and being small they are easy to store, yet can be readily used due to their size.

Your second duty of care when it comes to noise is ensuring that your business does not produce too much noise externally, if it does and people complain about it then you can find that the council will be along in no time to check it, so again accurate monitoring of your external noise is also vital. If not you could find yourself on the wrong end of an environmental notice.

So if noise is an issue for your business or you think it might be, then invest in a good handheld sound level meter today.

What to Expect From a Floatation Tank

Everyone is on the lookout for that peace and quiet and one of the ways to get to it is with a floatation tank. Also called an isolation tank, this was first created by John C Lilly, way back in 1954. His main idea was to try and study the effects of sensory deprivation on an individual. This tank was meant to be soundproof and with salt water, just at room temperature and enough to enable an individual to float.

Over the years, this research tool came to be used as a means of relaxation or as a prelude to meditation. Several modifications were made to enable a person to float in it without the use of a breathing apparatus, thus making the experience all the more silent and effective. Today, Epsom salt is added to the water in the tanks, increasing its density and allowing a person to float with their face above the water. With your ears submerged, sound is largely cut off and you can enhance that by wearing ear plugs as well.

As you let your body float on the water - the natural temperature of the water prevents you from feeling anything and soon you lose a sense of distinction between body and water. This elevates you to a whole new place and the body goes through three levels of experience with the last one precluding sleep.

Ideally one should enter a floatation tank in the nude. A swim suit is allowed but the elastic hampers the complete experience as it tends to constrict certain parts of your body preventing it from relaxing. Since Epsom salt water is not often replaced you will need to have a thorough bath before you get into to water. Means of cleaning the water are left to surface skimmers as well as filtering the cartridge. Ultraviolet sterilization also helps in keeping micro-organisms at bay. A system of convection in put in place to ensure that the water gently flows under the person and allows them to stay centered in the water.

All the plumbing in a floatation tank is generally made of plastic. A very high quality tank is made of medical grade stainless steel. This also does not crumble with the constant presence of salt. A good floatation therapy unit will also have a shower unit placed close by so that you can go from the stall to the tank without having to towel off. These tanks come with built in plumbing systems so that water can be easily drained and refilled when needed.
