About Us

Mid year 2009, EarZin co-founder Dr. Garth Gobeli (PhD, Physics) visited an audiologist at his wife’s urging for a hearing evaluation.

The story is:

The audiogram showed that he had advanced age related hearing loss (Dr. Gobeli is now 83 years old). He was stunned that the recommended hearing were priced at $5400. He knew several of his friends also suffered this hearing loss and all of them complained about how their hearing aids worked as well as the price. Several of them wore their hearing aids in their dresser drawer. He paused and decided to look further into hearing aids and how they function.

He looked carefully at the audiogram and recognized how to design a device that could compensate for the age related hearing loss. He decided that it was certain that an analog instrument could be designed and fabricated that would perform better than the digital hearing aids that were recommended to him. Moreover it would cost significantly less than the digital hearing aid’s price.

In less than a year, with the help of a friend who was an electrical engineer, the instrument that is now known as the EarZin was designed, tested, and after some personal investment, it was manufactured. Its description and performance are noted elsewhere on this website.

He found that it provided a nearly normal sounding hearing experience, with the higher pitches of sound clearly heard and understood. For the first time in many years, the sounds of crickets, locusts, and small songbirds were heard. The hearing experience was natural. It was just what he remembered from many years ago. Other users of the EarZin have made this same observation.

To those with severe age-related hearing loss: Dr. Gobeli understands and shares the frustrations with hearing problems.

The EarZin effectively and affordably restores quality hearing for those that suffer from substantial age-related hearing loss. Give it a try. You will believe your ears.

EarZin Advantages Overview

The main reason for Hearing Aid non-ownership is almost always PRICE and poor performance for age related hearing loss. The price of a pair of quality hearing aids is $4000 to $6500. The company’s product, the EarZin will be priced at $395 for both ears and has distinctly superior performance.

The EarZin amplifies sounds to at least 10,000 Hz, in the soprano hearing range, at high frequencies that contain the sibilant sounds (“s”, “f”, and “th”) that are clearly important for easy speech comprehension. The distinction between the singular and plural of many words, such as word and words also is impaired. Conventional hearing aids have significant amplification only to the 3200 Hz region. Even for the newly advertised “high power” hearing aids the upper hearing range extends to only about 4,200 Hz.

The EarZin has an auxiliary input jack. This feature permits a cell phone to be connected so that both the ring tones and the audio conversations are channeled through the EarZin amplification circuits.

The EarZin uses two distinctly separated ½ inch control knobs to adjust the volume. Conventional hearing aids use very small (less than 1/8 inch diameter) controls that require adjustment via a finger-nail or some sort of tool.

The EarZin uses a rechargeable Li-ion battery similar to that in a small cell phone. There is no necessity of tediously changing very small batteries. A single charge lasts in the EarZin for more than 48 hours. The Li-ion battery may be recharged many hundreds of times before needing replacement.

The input microphones of the Ear POD are located in a small, attractive case that is separated from the earbud micro-speakers by some 10 inches or more. This factor reduces the feedback problems so that quite high amplification factors can be used without causing “feedback squeal”.
