About 30 years ago my father brought his hearing aids in for repair to a local hearing aid shop.
Use Coupon Code 93504B5 when you purchase your new hearing aids to receive a FREE box of 40 hearing aid batteries! Versata uses the advanced version of Phonak's CORE (Communication Optimized Real-audio Engine) technology. For most users the advanced level used in the Versata will yield exceptional performance at an affordable price. Multiple memory settings can be programmed into the aid to give the user the ability to cope with changing sound and noise environments with the push of a button. Volume control is generally considered to be a manual adjustment that the user can control.
This feature helps make hearing aids acoustically comfortable by dampening sudden loud noises, such as a dropped dish. Wind noise is an important feature for those that spend time in the outdoors by reducing the roar of wind across the microphone. Acoustic Feedback, is also known as squealing, buzzing, 'your aids are talking to you', etc. Communication from one hearing aid to the other is a very low strength signal designed to keep both hearing aids operating in the same mode at the same volume. Being able to couple your hearing aids with a BlueTooth-enabled device, such as a cell phone, allows phone conversations to be heard through your hearing aids. DAI is only on Large and Full Size hearing aids due to the need for terminals on the outside of the case.
Conventional Hearing Aid Batteries cost less than a dollar per battery and are very easy to change. Seamless switching through 7 tunable configuration points to keep amplification optimized for any sound environment. Phonak, is arguably the hearing industry's leader in sound processing with its CORE technology. Advanced Core is used in Audeo YES V, Versata, power aid Naida V, and pediatric aid Nios micro V. Standard CORE is used in Audeo YES III, Certina, power aid Naida III, and pediatric aid Nios micro III. Premium CORE offers the leading edge of technical advances in noise reduction, feedback reduction, directionality, and automatic switching between environmental programs. Advanced CORE is slightly less advanced than Premium but still a very competitive sound processing technology.
Standard CORE offers a way for people to get some of the most functional features of CORE at an affordable price. When choosing among the levels of technology offered, we suggest looking at the amount of noise you are in on a regular basis.

In situations where the probe tube is not inserted deeply enough into the ear canal, negative RECD values may occur in the higher frequencies above 3000 Hz.
When all RECD values are negative (as seen in Figure 3 below), a blocked or crimped probe tube may be the cause.
Otoscopic inspection of the ear canal prior to measuring the RECD should indicate when some situations such as tympanic membrane perforations or wax are present. Although age-related RECD averages exist, repeated studies of RECD results in children (Feigin, et al, 1989; Bagatto, et al, 2002) have indicated that inter-subject RECD variability is high across age. Age-related averages do not take into account the unique characteristics of an individual earmold such as canal length, tightness of fit, or venting, which all can affect the real ear response. Middle ear effusion and tympanic membrane perforations are the most common middle ear conditions that affect the RECD response. Most pediatric guidelines recommend that the RECD be repeated whenever the child has an earmold change. Upon looking at the hearing aids the salesman said, “Those are sealed units and can’t be repaired.” With that he through the hearing aids in the trash can! I got into the hearing aid repair industry, and years later I repaired those hearing aids for my dad.
It is available in two mini-BTE open ear models and two BTE models, and is capable of fitting hearing losses from mild to severe.
Digital is newer and considered to be much more flexible, capable of doing more operations, and the only technology used in modern hearing aids.
Hearing aids are built so that this group of frequencies (250 to 6000 Hz) is divided into smaller groups, called bands or channels. All hearing aids have automatic gain control designed to make soft sounds audible and loud sounds tolerable.
Using DAI allows other devices to connect directly to the hearing aids and input their audio signal. The first and most common possibility is the result of a loose-fitting earmold or an earmold with a large vent. In this case, the RECD measurement may include the resonance characteristics of the entire middle ear space, creating a negative RECD value in the low to mid frequency region between 750 and 1500 Hz (Martin, et al, 1997) . Figure 2 below illustrates negative high frequency RECD values resulting from short probe tube insertion. The tube could be blocked by wax or by incorrect placement of the tube against the ear canal.

The audiologist should troubleshoot the probe tube and its placement in the child's ear canal when RECD results are unexpected. Individual variability of measured RECD values ranges from 10-14 dB across frequencies for all ages studied. TM perforations were discussed above, with the effect being a negative RECD value in the low to mid frequency range. When this recommendation is applied to infants and very young children, it can mean frequent RECD measures as new earmolds are needed as often as every 2-3 months when infants are growing rapidly.
My father bought new hearing aids that day (but also dug his old hearing aids out of the trash when the salesman left the room).
The mini-BTE open ear models are small enough for a discrete fit and come in a variety of case colors. In this case, amplified low-frequency information leaks out around the canal or through the earmold vent. Because negative RECD values may be present at higher frequencies than seen with venting, it is less likely to result in estimated real ear gain errors. A 10-14 dB difference between an average RECD value and an individually measured response could mean the difference between audibility and no audibility of speech sounds for some children. Therefore, the average RECD for a 4 month-old would be the same as the average RECD for an 11 month-old. On the other hand, middle ear effusion with increased stiffness of the TM often creates larger positive RECD values across the frequency range tested. Using one ear's measured RECD as the predictor for the second ear can be an efficient compromise when faced with such frequent retesting. However, unamplified low frequencies may also enter the ear canal through these same sources.
Figure 1 below contrasts the measured RECD values for an intact eardrum (Left ear, left panel) with an eardrum that has a perforation (Right ear, right panel). It could also mean the difference between a safe versus an excessive real ear saturation response level. More recent data from Bagatto, et al (2002) has provided more specific age categories for infants, but different test systems and software applications may still be applying the older, larger age categories. Errors in predicted real ear amplified gain may occur with large negative RECDs (greater than -5 dB), especially when the gain of the hearing instrument is minimal at the same frequencies where the negative RECD values occur.
