The two most common technologies used in hearing aids are analog and digital. Digital is newer and considered to be much more flexible, capable of doing more operations, and the only technology used in modern hearing aids.
Open Fit Type Hollow Tube & Dome
Human speech ranges in frequencies roughly from 250 to 6000 Hz. Hearing aids are built so that this group of frequencies (250 to 6000 Hz) is divided into smaller groups, called bands or channels.
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.
Technology Level Economy
Volume Control
Volume control is generally considered to be a manual adjustment that the user can control. All hearing aids have automatic gain control designed to make soft sounds audible and loud sounds tolerable. This is done automatically within limits programmed into the device.
Available with Remote
On-Board Control Type
Controls on hearing aids usually have one or more of:
1. A momentary button used to change from one memory to the next
2. A button used to increase the level of volume
3. A rocker switch where pushing on one end does one function while the other end does another function
4. A wheel that will control volume
Memory Button & Volume Control
Remote Control Available
Remote controls for hearing aids are small enough to comfortably fit in a pocket. A remote control will enable more functions than can be put on a hearing aid itself.
Directional Microphones
Microphones are the electronic component that picks up sound. Microphones are very small and can be made to pick up more sound in one direction than all others. This is called a directional microphone.
Noise Reduction
Technology to separate voices from other sounds is continuously being improved. Each manufacturer has a patented process and trademarked name for noise reduction.
Sudden Noise Protection
This feature helps make hearing aids acoustically comfortable by dampening sudden loud noises, such as a dropped dish.
Wind Noise Protection
Wind noise is an important feature for those that spend time in the outdoors by reducing the roar of wind across the microphone. This feature is improving but is not effective in gusty wind conditions.
Feedback Management
Acoustic Feedback, is also known as squealing, buzzing, 'your aids are talking to you', etc.
Telecoils help with telephones that are rated hearing aid compatible.
Aid-to-Aid Communication
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.
Bluetooth Capable
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.
Direct Audio Input (DAI)
DAI is only on Large and Full Size hearing aids due to the need for terminals on the outside of the case. Using DAI allows other devices to connect directly to the hearing aids and input their audio signal.
Battery Size/Color
Conventional Hearing Aid Batteries cost less than a dollar per battery and are very easy to change.

Precise Review

Phonak is arguably the hearing industry’s leader in sound processing with its CORE technology.

Phonak has released CORE in three levels; Premium, Advanced, and Standard. Certena uses Standard CORE.

Where Phonak offers the three levels of CORE in its model line.

  1. Premium CORE is used in the Exelia Art, Audeo YES IX, and power aid Naida IX.
  2. Advanced Core is used in Audeo YES V, Versata, power aid Naida V, and pediatric aid Nios micro V.
  3. Standard CORE is used in Audeo YES III, Certena, power aid Naida III, and pediatric aid Nios micro III.
Explanation of levels:

  • 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. All of the technology levels will sound essentially the same in quiet conditions but the top levels will sound better and be more functional in above average noise conditions.

Certena makes a great choice for those that want a reliable and economical hearing aid from a leading manufacturer.

Certena will connect with most audio devices using Phonak accessories.
