World-Class Hearing Aid Technologies:

Meenakshi Speech and Hearing Clinic is equipped with cutting-edge ear technology and state-of-the-art computerized testing equipment. We offer sophisticated hearing aids and a fully furnished setup for audiological and speech tests. Our soundproof double room ensures accurate audiological evaluations, where patients respond to both sound and speech.

Understanding How We Hear:

Our ears and brain work together to receive and interpret sound impulses, starting with the outer ear collecting sound waves and transmitting them to the eardrum via the ear canal. Vibrations created by the sound waves cause movement in the middle ear’s three bones, particularly the stapes. This impacts the inner ear fluid and stimulates the cochlea, which contains hair cells that trigger nerve impulses sent to the brain. The brain processes these impulses into recognizable sounds.

What is a Hearing Aid?

A hearing aid is a battery-powered electronic device that amplifies sounds for those with hearing loss. It consists of:

  • Microphone: Captures and converts acoustic sounds to electronic signals.
  • Amplifier: Boosts the electronic signals.
  • Receiver: Turns electronic signals back into sounds and delivers them to the ear.

Types of Hearing Aids:

  1. Behind The Ear (BTE): Hooks over the ear, resting behind it. An ear mold inside the ear canal receives amplified sound.
    • Suitable for all ages and types of hearing loss.
    • Visible but highly effective, with new streamlined versions available.

  2. Open Fit/RIC (Receiver In Canal): Small devices using a tube or wire to send sound through a dome or speaker in the ear canal.
    • Best for mild to moderate high-frequency losses.
    • Less visible, doesn’t plug the ear canal.
  3. In The Ear (ITE): Custom-fitted aids that sit inside the ear.
    • Twin microphone design improves sound quality.
    • Best for moderate to severe hearing loss.

  4. In The Canal (ITC): Custom-fitted for partial insertion into the ear canal.
    • Suitable for mild to moderate hearing loss.
    • Less visible and easy to use with the phone.

  5. Completely In Canal (CIC): Fully fits inside the ear canal.
    • Minimally visible and well protected from wind noise.
    • Ideal for mild to moderate hearing loss.

  6. Invisible In Canal (IIC): Deeper fitting than CIC and practically invisible, pulled out with a nylon thread.
    • Custom-made for a perfect fit.
    • No hard edges for a comfortable feel.

Hearing with both ears 

The Importance of Hearing with Both Ears

Hearing with both ears, known as binaural hearing, offers key benefits such as:

  1. Understanding Speech in Noise: Two ears help the brain pick up speech more easily in noisy environments and enable selective listening to focus on important conversations.
  2. Locating Sound: Binaural hearing helps identify where sounds originate, making activities like crossing streets safer.
  3. Avoiding the Head Shadow Effect: Sounds coming from your ‘bad side’ are often muffled due to the head blocking the way. Hearing with both ears helps minimize this issue.
  4. Enjoying Music: Binaural hearing enhances music enjoyment by delivering a fuller, more natural sound.
  5. Speech Development in Children: Hearing with both ears supports better speech understanding and language learning, crucial for childhood development.
  6. Bimodal Hearing: Combines a cochlear implant and hearing aid for improved speech understanding, music perception, and overall satisfaction.
  7. Bilateral Hearing Implants: Ideal if a bimodal solution is insufficient. They may significantly improve speech comprehension, especially for children, by providing input to both ears for better auditory development.
