Just as there are different hearing problems in terms of symptoms, which are actually expressed and the physiological cause of hearing loss, so there are different hearing tests designed to locate the nature of the problem, its source, and accordingly the ideal treatment. It is of great importance to accurately locate the specific hearing problem of each one, only in this way can full customization of hearing aids and other complementary accessories be done that can definitely improve the quality of life of those suffering from various hearing problems.
Diagnosis of a hearing problem
The first step when diagnosing hearing problems and the nature that causes them is usually a standard hearing test, a test that consists mainly of two parts. The two parts of the test are assessing the hearing threshold for pure sounds that include one frequency – beeps for example – in addition to tests for understanding and hearing speech. These hearing tests are performed in an airtight room, with the subject wearing headphones. The examination is performed by a qualified audiologist, who sits with the appropriate equipment outside the room and with eye contact with the subject.
The actual test includes a hearing threshold test for speech – repetition of words heard at varying intensities, a hearing threshold test for pure sounds (AC air conduction) – marking the tester every time you hear a beep, a hearing threshold test for pure sounds in bone conduction – a special ear that transmits directly to the auditory nerve and beeping And finally a discrimination test – repeating simple words at a constant intensity and easy for the subject to hear. The various parts of these hearing tests are recorded on an audiogram (graphical diagram of the hearing thresholds and test measurements). According to the test, you should see what the level of hearing loss is, try to understand the source of hearing problems, and so on.
Diagnosis of hearing problems using a tympanometry test
Hearing problems can result from problems with the eardrum or dysfunction of the auditory organs inside the middle (middle) ear. A tympanometry test is designed to detect hearing problems that originate in the middle ear, the test is sometimes called an acoustic response test in Hebrew. A medical instrument called a tympanometer is used for testing, an advanced earpiece is inserted that contains a tiny speaker, a microphone for measuring the repeated sound, and a tube for regulating the air pressure in the ear at various pressures. The test actually examines the pressure units created due to the return of the sound heard by the eardrum – the results are measured in a dedicated graph called a tympanogram.
These acoustic hearing tests actually measure the efficiency of the auditory organs and the system in the middle ear – so a normal result does not necessarily indicate the absence of hearing problems originating in the inner ear or the nervous system for example.
Hearing aids are sophisticated accessories that include a wealth of innovative technologies designed to improve hearing, even in acoustically challenging situations. With the technological advances that have taken place in recent years in the field of electronics, communications and acoustics, a combination of wireless capabilities in hearing aids has begun.
I want a modern, wireless hearing aid
Wireless hearing aids have clear advantages: the ability to communicate between the two hearing aids on either side of the head. Ability to connect (interface) to electronic equipment and accessories. It is easy for those who are still leading an active life and want to have a more discrete look. You should always look at hearing aid features and capabilities before making any purchase.
Communication between two (two-sided) hearing aids has two notable advantages: the ability to operate and synchronize – such as changing the volume or programs of the devices; And joint decision-making ability about how amplification is required in each situation. For example, when one side is loud and speech is heard from the other side, the hearing aids will make a decision about landing the noise on one side (the loud one) and focusing the speech on the other side to get the best hearing to result in the given situation. The ability to connect to electronic devices is a huge advantage of wireless technologies: connection to a mobile phone while transmitting directly to the hearing aids instead of attaching the phone to the devices. Listening to a lecture remotely as if the user of the devices were sitting in the front row. Listening to a TV without raising the volume and without disturbing the rest of the viewers and occupants of the house. The wireless transmission also helps to overcome the weakening of the voice signal as the distance increases and also the noise circulating in the space between the accessory and the device.
