Listen to what it is like to have tinnitus: from a kettle boiling to static TV

For some, tinnitus sounds like a high-pitched wine that registers in a tone of 4000Hz (stock)

From a boiling kettle to flying insects, the eight most common noises that millions of people suffering from tinnitus have to tolerate every day are shown below.

About 15 percent of adults in the UK suffer from tinnitus, which makes them hear everything from static hums, electric sparks and even roars in their heads without an external source.

It is believed that tinnitus occurs because a person's brain can not filter the different sounds that their ears pick up. This may be due to a breakdown of certain chemical messengers in the vital organ.

Mark Williams, chief audiologist at The Tinnitus Clinic, London, told MailOnline: "Tinnitus is the involuntary perception of sound.The main thing that decreases the quality of life is high anxiety, loss of sleep and inability to concentrate. "

If any of the following sounds familiar, it may be worth going to see your GP.

Mr. Williams describes the audio clips as a & # 39; guide & # 39 ;, and adds: & # 39; Align the correct treatment with the correct sound. Sound therapy can be adapted to the type of noise a tinnitus patient hears. "

He also urges the sufferers to try to stay calm, and anxiety only makes the symptoms worse.

"When you lose a hearing degree, the brain tries to compensate and, for some, the compensation is too aggressive.

"Over time, it tends to improve as people become less anxious about it, so the brain filters out the noise," Williams explained.

White noise is often recommended to tinnitus patients to cover up the incessant buzzer they hear.

However, research published earlier this month suggests that the background noise of static white television noise and hair dryers may be aging.

Although it helps to mask background sounds, white noise can reduce the brain's ability to adapt to incoming information.

Scientists discovered that listening to white noise, even if it is not strong, speeds up the aging process of a person's brain by breaking down certain chemical messengers.

The study's author, Mouna Attarha, of the University of Iowa, said: "The increase in evidence shows that the brain is negatively reconnected when it receives random information, such as white noise."

It is believed that the aging process that takes place in the brain when exposed to white noise is similar to that which occurs in patients with tinnitus.

HOW DOES ACTIVE NOISE CONTROL SOUND-CANCELLING TECHNOLOGY WORK?

Active noise control is found in high-end noise canceling headphones and promises to reduce the amount of ambient sound entering the user's ears.

Each headphone speaker is equipped with a microphone, which allows the system to detect the waveforms of the sounds that enter them.

Then it generates an exact match for these sound waves, which are then inverted.

When these two opposite signals meet, it cancels offensive external sounds.

Some systems claim to be able to reduce noise by up to 90 percent, although in some models it can be as low as 50 percent.

The technology has been around for several decades, but has been used relatively recently in commercial headphones.

Even more recently, it has begun to be applied in industrial situations and other public situations.

Full-size speakers equipped with the technology are used to cancel the disruptive noises of transformers, compressors and other low frequency machines.

Several institutions are also working on ways to incorporate it into residential and commercial buildings, such as homes, stores and offices.
