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 Call for Info.
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 Standard
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.
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.
Warranty 3 years
Loss/Damage Warranty 1 year
