Are the hearing aids advertised on TV any good?

Hearing aids for smart tv

Knowing how our auditory system works can help us understand more easily to what extent it can be affected by prolonged exposure to an intense noise level, so it is worth dedicating a few lines to it. Its function is to transform the pressure variations that propagate through the air in the form of waves, which is what we know as sound, into electrical impulses that will be processed and interpreted by our brain. This is the reason why this system, which is made up of several organs, behaves like a sensor without which our brain would not be able to receive the information that allows it to interpret the sounds that occur around us.

The hair cells have different degrees of sensitivity, a characteristic that allows them to identify the entire spectrum of audible frequencies, from the lowest, or bass sounds, to the highest, or high-pitched sounds. The transformation of the mechanical vibrations to which these cells are subjected into electrical pulses to be interpreted by the brain is a complex process based on the ability of these sensory cells to identify the entire spectrum of audible frequencies. Those housed in the lower region of the cochlea are responsible for identifying the higher frequencies, between approximately 20,000 and 3,000 Hz, while the hair cells in the innermost part of this snail-shaped tube are specialized in identifying the lower frequencies, which extend down to 20 Hz.

Vibrations are transformed into sound when they reach our inner ears directly without passing through the eardrum. An operation that has several advantages over traditional headphone systems.

The European Union has ordered manufacturers of smartphones and audio players to limit the volume on headphones, and to display an alert to users when the volume exceeds certain maximums. The aim is to protect citizens from developing hearing problems at a young age.

The third advantage is that the sound coming through bone conduction is more faithful, although less clear. If we listen to recordings of our voice through bone conduction, it will be more similar to how we hear it when it comes out of our mouth, avoiding the sensation of sound dullness when we hear our voice through a loudspeaker or headphones. The reason is simple: our words reach our ears through the bones of the skull, just like this type of loudspeaker.

Have you ever wondered why our voice sounds different when we emit it than when we hear it in a recording? Well, it is partly due to the phenomenon of bone conduction, by which the skull conducts the low frequencies better than the air when speaking, so we perceive our own voice with a lower and clearer tone compared to those who listen to us.

If you are wondering if the bone conduction is real or if part of the sound is introduced through the ear canal, we have tested the headphones using traditional earplugs (included by the manufacturer in case we ever want to isolate ourselves from the ambient sound) and we found that the alternative bone conduction that is advertised is really used.

There are several ways to do this. You can start with your primary care physician, an otolaryngologist, an audiologist, or a hearing aid specialist. Each has different training and experience. Each cannot be an important part of your hearing health care.

An otolaryngologist is a physician who specializes in the diagnosis and treatment of diseases of the ear, nose and throat. An otolaryngologist will try to find out the cause of your hearing problems and offer treatment options. He or she may also refer you to another hearing professional, such as an audiologist. The audiologist has received specialized training to identify what type and how severe your hearing loss is. He or she can also tell you what treatment options you have. In addition, audiologists may be authorized to fit you for hearing aids. Another professional who can fit you for hearing aids is a hearing aid specialist or audiologist. The hearing aid specialist must be licensed by the state to perform basic hearing tests and evaluate the results, offer counseling, and fit and test hearing aids. Before you can be fitted for a hearing aid, you must be examined by a physician. Federal law allows you to waive this right if you do not wish to be examined before purchasing the hearing aid.
