A hearing aid or corrector is a technical medical device designed to allveiate hearing damage and to aid hearing loss. There are many and numerous styles, types and shapes of hearing instruments.

The majority of new ranges are designed exclusively for individual loss, that is they are custom made to suit. At St. John's we provide a large range of earing aids to match each particular hearing loss with the most appropriate hearing device.

St. John's provides the entire Starkey line of hearing instruments.

Completely-In-The-Canal (CIC)

In-The-Canal (ITC)
An ITC aid rests more deeply within the ear canal. Starkey's most popular hearing instrument maximises the ear's sound gathering design in a convenient size. ITC instruments offer the right combination of appearance and affordibility to meet a variety of hearing losses. The ITC range includes , and .

In-The-Ear (ITE)
An ITE sits neatly inside the ear canal. Starkey's most flexible hearing instrument allows for a variety of performance options that would have previously required a larger instrument.

Sirrus, Sequel and DiRx are some of the most popular custom made products. The Sirrus programmable covers losses up to severe. Sequel analogue products provide exceptionally low distortion, delivering a clean, crisp sound. Both Sirrus and Sequel are available in all custom styles.

The inner ear is extraordinarily sensitive to the tiniest differences in sound loudness and pitch. To recreate this, Aries II digital sound processor divides incoming sounds into more narrower sounds - nine in all - each with its own very precise adjustment capabilities.

The nine channels work with circuitry that reacts instantaneously to sudden changes in sound levels and an exclusive technology to prevent over-amplification of soft sounds and noise in quiet surroundings. Aries II provides a more realistic and natural sound quality.

Unlike some digital aids, wearing Aries II doesn't mean sacrificing discreet appearances. Thanks to advances in Starkey design and manufacturing, Aries II is available in all sizes - including the virtually invisible CIC.

Containing the latest breakthroughs in Digital hearing science, Doviri is designed and engineered to help you rediscover the joy of hearing. Utilising the most advanced, 100% digital signal processing (DSP) design, Doviri preserves and delivers an increased dynamic range in both high and low ranges.

What's more, Doviri is the only fully programmable digital hearing system that offers both a custom filter system with truly independent multi-channel compression. Because of the way your instruments respond to low and high frequency sounds, loud sounds are less likely to become uncomfortable while soft sounds can be understood.

Doviri also features a multi step feedback management algorithm which first senses the probability of feedback before it can begin forming. Sophisticated filtration is then automatically programmed into your instrument to prevent feedback's onset - even if volume is increased.

The fitting of your digital BTE is important - why compromise your fitting with inadequate earmoulds?

Thankfully, DigiMold, the new digital friendly earmould is now available. Blending supreme comfort and superior acoustic coupling properties, each DigiMold is handcrafted to discreetly blend with the users ear.

The precisely sculptured nature of DigiMold significantly reduces the necessity of activating any on-board feedback management algorithm, thereby improving speech recognition by preserving necessary sound cues.

DigiMold is a partnership between clinicians and the Starkey Earmould Facilities. Clinicians must follow a well defined, disciplined approach to securing an accurate replica of the patients' ear together with a thorough audiogram. Once this is achieved, Starkey have perfected a process of earmould manufacture, that guarantees an appropriate fitting earpiece with built-in flexibility for fine tuning of the hearing instrument complimentary to the fitting software.

A common complaint of many hearing aid users is the inability to understand speech in a noisy environment. Currently the only solution to this problem is to improve the signal-to-noise ratio (SNR) available to the user. Directional technology is the single most effective strategy available to improve speech recognition in noise and reverberation by emphasising sounds in the forward direction more than sounds from the sides and behind. In other words, improving the SNR.

DiRx is the first dual-microphone system engineered for custom full-shell and half-shell hearing instruments. The smaller, flexible design of DiRx incorporates two matched omnidirectional microphones in conjunction with Digitally Optimized Directionality. The two microphones are digitally tuned to match the microphone circuitry of each pair, providing optimal directivity for each DiRx system. This means the user will benefit from the improvement in directionality without compromising gain or sound quality.

Sequel is the bridge between analogue and digital, the affordable link for many hearing aid users currently on entry level technology, who want to experience a whole new sound of clarity without distortion.

As the affordable foundation stone for new users, Sequel offers an excellent listening experience immediately, and comes in all sizes from BTE to CIC. Totally flexible for your lifestyle needs and combining technology and size is the Sequel CIC, (completely-in-the-canal) which utilises the advanced, low distortion analogue technology of the Sequel circuit within the popular size of the CIC.

When a hearing loss impairs your ability to clearly understand everyday sounds and conversations, you're missing vital portions that resonate and enrich your life.

Acoustically speaking, resonance has a much greater impact on effective hearing. Regardless of your ability to hear, your ears offer some amazing natural amplification abilities all on their own.

Our ears' built-in hearing aids..
The intricate shape of your outer ears act as sophisticated sound gathering devices, amplifying as well as directing sound waves into the ear canal.

Further amplification takes place in your canals, thanks to their naturally occurring acoustic resonance. Like tuning forks and pipe organs, your ears possess physical capacities that actually amplify sounds at a certain frequency, usually between 1200-3000 hertz.
