![]() This Audio DB Meter complies with IEC651 Type 2 and ANSI S1.4 Type 2,with the measuring scope from 30 to 130 dB and automatic shifting function, A and C Frequency Weighting mode selection.And backlight auto power off function is provided, high-reliability and well-designed high-efficiency power supply circuit make the battery more durable Features with backlight feature,it is appropriate for gathering the sound date at night.The Mini Handhold Digital Sound Level Reader is compact, lightweight,easy to use,it is not only extremely wear-resisting, but also elegant.If you can’t hear someone when they talk to you then it isn’t too loud. A good way to remember this is by thinking that if you can hear the sound, it is too loud. Knowing your safe dB level is important for your health. ![]() There is a safe dB level, which is around 70 decibels, and at 80 decibels you will need to wear ear protection. This is not for everyone and can be uncomfortable to wear for longer than 15 minutes at a time. The most common type for noise work is called the “earplug”. These do not fit over ear canal sensors, if you have them.Ĭlosed Cell Foam Ear Plugs, these again are a single insert but with some sort of silicone liner around the foam pad. These are designed to go in the ear canal but not all brands fit all people. Rigid Foam Ear Plugs, these are a single insert type of ear piece. They can be expensive however, up to $100 for a pair of large ear muffs. They block the sound, making it impossible for you to hear anything but the sound that you put in there. Ear muffs are also very popular among workers and people who want to prevent the sound from hitting them directly. The most common types of ear protection are:Įar plugs are very cheap and popular, they have to be removed for swimming, showers and sleeping. You will need ear protection if you are exposed to noise above 90 decibels for more that 15 minutes. For example: If a machine runs at 85 decibels all day long, then the average level would be 70 decibels after 8 hours. This is will work well for long term measurements in places such as offices or factories, where they want readings taken every 10 minutes of how loud something is running. How to measure dB level with a sound level meter These one shown below is very good, called “Sound Meter”Ī stand alone device that you will need to buy, called “Sound Meter Plus”, these are the best for professional use.Ī sound meter will display the dB level as well as the decibel level that is above or below this range. Mobile Phone App, these are the best, as they are on your phone and you can take them with you. This will work a lot better if you use a sound meter. How to measure dB level with a sound meter This is not a good measure, but if you are able to hear the person, then you are in the safe zone. Today, our industry-leading BR 600 backpack blower operates at 75 dB, as well as the NEW BR 700, and our ultra-quiet BR 500 at a mere 65 dB, not much louder than two neighbours chatting about the great job STIHL power tools do.If you are 3 feet away from someone, and they have to raise there voice to be heard, then you are probably to somewhere to loud. Recognizing this, STIHL has developed new, quieter engine technologies and re-designed the fan-wheel to make the blower sound less offensive. Earlier versions of this product had high decibel readings and the tonality of the machine (a whiny sound) was somewhat bothersome to many residents. One tool which has come under considerable scrutiny is the leaf blower. Ordinances have been put in place governing time-of-use rules for power equipment to ensure the comfort of residents. In recent years, as municipalities have grown, they have become more concerned with noise levels in their communities. Check out the variety of options at your local STIHL Dealer! Although many tools in our outdoor power equipment line-up operate within safe decibel levels, STIHL recommends the use of hearing protection when operating any power tool. Anyone working in a 100 dB environment should limit their exposure to two hours per day. Government research suggests the safe exposure maximum limit is 85 dB for an eight-hour work day. For example, a 3 dB decrease affects a 50% change in sound pressure levels, while a 6 dB drop reduces exposure by 75%.ĭecibel levels are important to professional users and homeowners alike who wish to avoid noise-induced hearing damage. The relationships among the above values are algorithmic, not linear therefore, the simple assumption that a sound with a 100 dB level is twice as intense as a sound with a 50 dB level would be incorrect. At close range, sounds that reach 120 decibels (about the sound of an ambulance siren) are painful to our ears. The decibel (dB), which describes the relative intensity of a sound, is based on a scale containing values ranging from 0 – 194, with zero representing the weakest sound audible to humans.
