Frequency Malfunctions in Bluetooth Hearing Aids

 Hearing aids with bluetooth technology have certainly caught my attention when I discovered how remarkable they truly were.


The amazing sound quality allowed me to hear tones I’d lost years ago.

To put on a new set of hearing aids without an adjustment period had captured my heart and to not feel overwhelmed during adjustment periods.


However they do come with pro’s and con’s that certainly will need to be weighed in before purchase.


My overall personal experience wearing bluetooth hearing aids have exceeded a positive outcome on my quality of life.



I’ve been wearing hearing aids since I was 5 years old. I’ve had the experience of wearing analog and programmable hearing aids. Bluetooth compatible hearing aids have by far been a sensational experience being able to hear tones I’d hadn’t been able to hear for years.


However today’s technology requires us to weigh in radio frequencies and other bluetooth technology that may hinder a person’s ability to hear quality sounds from malfunctions in bluetooth frequencies.


Especially in times of need…



With the basic principle of another’s “Bluetooth Headset” at the doctor’s office, scheduled services through cellular phones, security services,  stores, restaurants, etc.


With the occasional frequency interferences in public restrooms and alternative locations.


The necessity that we come to rely on may stream frequencies that are gargle or muffled, static or screeching sounds like a fax machine, the automatic on-and-off of a person’s hearing aid device makes it difficult to communicate with others.


There has been several occasions where I’ve had to politely ask others to not use bluetooth headphones when in private and public relations so that I could continue to engage in conversations.



Having hearing aids malfunction over frequencies becomes so bothersome that anything pertaining to what I may have needed becomes irrelevant if I cannot understand what is being said.

Hearing aid malfunction detection system
US 4049930 A


Disclosed is a malfunction detection system for detecting malfunctions in electrical signal processing circuits.

In a particular embodiment shown, malfunctions of a hearing aid in the form of frequency distortion and/or inadequate amplification by the hearing aid amplifier, as well as weakening of the hearing aid power supply are detectable.

A test signal is generated and a timed switching circuit periodically applies the test signal to the input of the hearing aid amplifier in place of the input signal from the microphone.

The resulting amplifier output is compared with the input test signal used as a reference signal.

The hearing aid battery voltage is also periodically compared to a reference voltage.

Deviations from the references beyond preset limits cause a warning system to operate. In the method of the invention, the input to a circuit to be tested is periodically interrupted and, for a fixed test time interval, a test signal is applied to the circuit to be tested.

The output of the circuit to be tested is compared with a reference signal, and deviation in amplitude and/or frequency between the two signals beyond preset limits triggers a warning.

During the test time interval, the voltage level of the power supply for the circuit to be tested is also compared to a reference voltage, and the warning system is triggered if the power supply voltage falls below the reference voltage.
