How to Avoid Echo in Mobile Calls and Why It Happens

Although we increasingly use mobile phones for more things than making calls, it is still key and we cannot ignore one of the failures that most affect this mode of communication, the problematic echo . It is an acoustic phenomenon that we have all suffered at some point on certain occasions and that can be a mere detail, but also become a serious problem if it occurs on our mobile.

This situation causes the receiver of the call to not be able to hear us well, receiving sound waves with delay on what we have mentioned and making it impossible in many cases to continue with the conversation. Although it may seem like an old failure, today in modern smartphones we continue to suffer from it, as advances in software have little to do with it.

The keys to not having an echo in calls

We must know that this peculiarity is usually caused in the opposite mobile where it is heard and therefore if we listen to the other person with an echo, we would have to let him know that the problem exists or he will never be aware of it. On practically no occasion does this problem appear on the speaker of the phones and if it were so, we could also discover it when listening to music or listening to WhatsApp audios and bringing the mobile closer to our ear as if it were a call.

Whatever your situation, we want to help you solve the complications with the echo or even if the problem lies with a friend or family member of yours, we invite you to share this article with all the solutions you need and thus get the next time you talk to him, you do not have to endure how annoying a conversation can be with the rebound effect of the voice that continually booms in our ears.

The room causes the echo

The most common thing that may be happening to us is that we find ourselves in an inappropriate place for the telephone, such as a very wide and open space in which the sound bounces easily, something that can also be found in rooms where there is no type. of furniture that bring sound waves and that bounce continuously. This situation affects a person-to-person conversation and much more on the smartphone since the waves continue to bounce and affect the investment tenths of a second later.

To prevent this from being repeated, all we have to do is open the door or the windows and even if the place has an echo, it will decrease significantly. In case of being very large, we always have to change rooms or even go outside since it is the place where the least bounce occurs and where the problem of echo in calls is not repeated under any circumstances.

The hands-free is the great cause of the echo

Another of the causes of suffering this in mobile phones is usually in the hands-free, when we activate the stereo speaker of our mobile and we stop having the microphone so close to our mouth, the sound has to travel through the air until it reaches it, causing the waves to disperse and cause confusion in our words. This does not always happen and may appear more often in places that meet the situations mentioned above and are prone to sound reflections.

If we are suffering from this situation, the only thing that should be done is to deactivate the hands-free and use it as we usually do, although in situations such as the car it will be necessary to continue being so. Some mid-range smartphones and almost all high-end smartphones already have more microphones that pick up noise and are able to identify the echo to reduce it and not affect calls as much.

Headphones are the culprits … or the solution

Now that we usually wear headphones while walking on the street, doing sports or even being at home, we can take advantage of its possibilities and speak through its integrated microphone to talk on the phone comfortably thanks to Bluetooth, although these headphones can often generate a annoying sound for the receiver because the headphones are not of sufficient quality or are not configured properly, something that is done from its own application. Higher-quality headphones have noise-reducing intelligence, but more basic ones don’t and can cause not only that, but also interference with other devices.

On the contrary, if the problem is in the internal microphone of the mobile we can try with headphones that integrate a microphone so that our receiver tells us if we are now being heard without an echo and we know that they have a problem that causes that annoying sound bounce.

Our microphone is damaged

As we have mentioned before, we can help ourselves with headphones to check if the error is in the mobile microphone, as long as we have already tried to change rooms, go outside and get away from the most possible scenarios for the effect of the waves sound on calls. Once we know that the microphone is the problem on the mobile monitor, we can choose to try a software update, entering the settings, although this will be the cause a little more times.

In most cases, the failures with the microphone have to do with a blow, which may have moved the internal microphone of the place and this causing the rebound of the echo to occur inside our mobile or even have water, which can also cause this result. We will have to go to the technical service in this situation to disassemble the mobile and check what is happening.

Coverage problem

As strange as it may seem, a problem with coverage may be part of the reason why we are experiencing that annoying echo in calls . When the range is not sufficient, the sound can distort and cause the echo to appear intermittently in the call. Faced with this situation, moving just a couple of meters can make the fault disappear and therefore we return to the recommendation to go outside if we are inside a building or rooms that are very surrounded by walls.

This not only appears in traditional calls for coverage, but also in internet calls, also known as VoIP that are achieved through various apps such as WhatsApp or Telegram. They need the best possible internet connection to function properly and otherwise cuts, echo or other failures appear that prevent the conversation from being properly maintained.
