In our society, many people want to protect their hearing by using the ear plugs and ear muffs. These products are very famous and easy to buy on the market. However, do you know how they work? I think it is a difficult question for many people. Because they do not care they only know their function, they are also very exciting when knowing a lot of things about these devices. In this article, I will have a brief introduction about how to work on the electronic hearing protection and amplification ear muffs.
Some things to know about the work of ear muffs
Actually, using the ear muffs to protect your hearing brings a lot of unexpected benefits for human health. This equipment can reduce the loud sounds, outside noises effectively such as the loud machinery, the gunfire…..
The inside of ear muffs, some electronic components as microphones will have a duty to receive the outside sounds. After that, these sounds will be reduced by an amplifier. At that time, your ear will hear the normal sounds from the inside of the electronic ear muffs.
You will think that this process will take a lot of time. It is quite wrong thinking. It is very quickly. For example, you must use the ear muffs when working in the noisy environments with your co-workers. You are preparing the machines and you need some bolts, nuts, or some necessary tools you must speak very loud to cover the surrounding sound. Immediately your friend will receive your requirement and take what you need. So you do not worry about wearing ear muffs will affect your work. In fact, it will protect your hearing as well as your health.
Beyond that, you should remember that the amplifier in the electronic ear muffs works very “smart”. You can see this through the following explanations.
- With the older models and cheap ear muffs, the technology of its work is also simple. The amplification of these ear muffs is often in the low level. When they pick up the external microphones which reach to the dangerous level the amplifier will turn off automatically. Besides, stopping the dangerous sound, the amplifier will continue to amplify the environmental sounds. Thus, you can see that although the ear muffs are old but the quality of its work is very good. Therefore, many people called this device that it has a smart capability.
- With the new model and more expensive ear muffs, the technology of its work is very great. We can be called like sound compression. This technology will also help you can hear all sounds in the outside but in the safe level without turning off or on automatically. In addition, these types of ear muffs, you can hear all sound even in the low- level sound because they are amplified appropriately. Also, the expensive electronic ear muffs contain two microphones on the outside and two speakers on the inside. These features will help users can determine the sound direction greatly. This is extremely necessary for hunting and some special situation in the army activities.
The important factors which you must consider about the electronic ear muffs
The specification of ear muffs will be very important to consider and check when you want to evaluate that they are good or not. Or this product can meet your needs or need. Some following features should be considered by the users.
Normally, you will be easy to see the NRR rating how much dB of the electronic ear muffs. Do you understand this number? The NRR is high it means that the ear muffs is enough good to protect your hearing. Depend on the noisy level in your working environment you can choose the suitable ear muffs with the suitable NRR. On the other hands, you need more protection when working in the large sounds for a long time.
Every ear cup will have at least one microphone to determine the sound direction which you will hear. Besides, the separate speakers in the ear cup will support for your hearing when sound is transmitted to. And it is better to have two microphones and two speakers in each ear cup.
You know that sound compression technology is the advanced feature in the expensive electronic ear muffs. Sound compression will help you hear with the continuity of sound without the on – off sound as the old and cheap models.
However, you do not worry you will hear the dangerous sounds because the ear muffs can not receive the risk signals from the outside. In fact, sound compression will self -adjust the loud sound and make it safe mode for the users.
The maximum volume
On the market, you can find out a lot of electronic ear muffs with the different models, sizes, colors, and prices. Each ear muffs will provide the different amplification. The best electronic ear muffs can have the NRR rating about 50 dB for the maximum amplification. Most of the ear muffs will guide users can turn on the safe level to protect your hearing. You can turn on the maximum volume. However, this is not always necessary for every time.
Independent ear cup controls
It is also necessary to have the independent ear cup controls for electronic ear muffs. This will help the users can adjust the different amplification of each ear cup. It is not always to have the same amplifications of two ear cups. Because you do not like it you want to have the difference. This often occurs in the shooters.
How to work on the electronic hearing protection and amplification ear muffs is not also too difficult to understand. Especially after you read the information in this writing. In addition, now you know why the electronic can reduce the loud sound quickly and effectively. To do it, the electronic ear muffs depend on a lot of different elements which I just explain above. I hope that you will understand about this device and you will have more experience to choose the appropriate electronic ear muffs which they can meet your needs in the best way.
