Hearing Aids in St. Peters, Missouri


A hearing aid is a small electronic device that is worn in or behind the ear. It is one of the many ear services we offer. The hearing aid is comprised of a microphone, an amplifier, a receiver or speaker, and a small microchip or computer chip. The microphones collect environmental sounds and transmit them to the microchip. The microchip analyzes the sound to reduce background noise and enhance the frequencies needed for better hearing. The sound is then amplified and sent to the ear via the speaker or receiver.

Hearing aids come in a variety of styles with a wide range of features. Once the audiologist assesses your hearing, he or she will help you decide which style is best for you. The design of hearing aids continue to get smaller, but choosing a smaller hearing aid can often compromise power needed for better hearing. The following are the most common styles.

Insignia Hearing Aids - Multiple Colors

  • Different colors to match hair and/or skin tone

BTE (Open Fit)

Once you’ve decided on the style, the audiologist will also help you decide which features best fit your lifestyle and needs. The advanced features vary depending on the technology level of the hearing aid. Technology levels can vary from basic amplification to advanced signal processing and sound quality. The cost of a hearing aid is generally dependent upon the technology level. Pricing can range anywhere from $1000 per hearing aid to $3000 per hearing aid.
