Shopping guide
To choose a sound level meter that fits our particular activities, it is necessary to pay attention to certain characteristics, such as calibration to obtain reliable measurements and the ability to keep records. For this reason, we have prepared this guide to buy the best sound level meter, with the most important information about this device.
Calibration
When making a comparison of sound level meters, it is important to take calibration into account, since it is a highly relevant technical requirement for the measurement result to have a real value. It is necessary to mention at this point that some products are calibrated at the factory, so they can be used with confidence immediately after purchase, however, other models must be configured, for which a calibrator will be necessary.
Calibration is basically the process in which the result provided by the sound level meter is compared with the information issued by another reference device. In the case of a sound meter, this activity must be carried out with an acoustic calibrator, which means that if we purchase a sound level meter that has not been calibrated, we must purchase a calibrator or invest in a specialized technical service.
On the other hand, we must point out that some manufacturers include a calibration certificate, that is, a document in which all the information on the conditions in which the device has been calibrated appears, so that the user has greater security when to make measurements. Generally, this is a very useful feature for experts.
In any case, if you buy a professional sound level meter, you should consider an investment for annual calibration, which is necessary if you want to keep the validity of the certificate.
functionality
Before asking how much a sound level meter costs, we must take into account the operation of the device, since the use we can give it depends on this. In this sense, one of the fundamental characteristics is the measurement range, which is expressed in decibels. We can say that most sound level meters work in a range of 30 to 130 dB.
Another important piece of information is the mode or frequency weighting. Some models have a button called A/C, which allows the use of weights A and C, in the first the meter has a response similar to that of the human ear, so it is widely used to protect workers in industrial environments where there are continuous noise, while in mode C the device gives more importance to low frequencies, so it is more used to measure intermittent or impact noise. For this reason, it is very important to define what we need the sound level meter for before choosing one model or another, since some devices only measure the frequency weighting A.
On the other hand, the sound level meters must have a spongy cover that works mainly as a wind protector, since otherwise the measurement could be affected by interference, decreasing the accuracy. In addition, it is necessary to check under what atmospheric conditions it can work, since a temperature greater than 40 °C can negatively affect most of this equipment.
Regarding connectivity, some sound level meters have software and a USB interface, so it is possible to connect the equipment to a computer to review the measurement directly in the desktop application and even store the data in Microsoft Excel documents, which allows for further analysis.
practicality
A basic home sound level meter is not only cheaper than a professional one, it can also be easier to use. In this sense, we must take into account the simplicity of the design, since a large number of buttons can confuse us if we do not have much experience. However, manufacturers usually include an instruction manual in the package.
In this order of ideas, it is good to mention the screen, which is usually LCD or LED, but it is important that it has light to observe the data in places with low lighting. In addition, it is advisable to choose a sound level meter that displays the results in large numbers, so that they can be easily read.
On the other hand, we must mention that most current sound level meters are small, light and battery-powered, therefore, they are portable devices, very practical to carry from one place to another. However, it must be taken into account that some come with batteries, but in other cases they must be purchased separately, which we must consider in the budget.
