Audiogram Analysis: Understanding their Characteristics, Interpretation, and Additional Details
In the journey of addressing hearing loss, understanding the various types of hearing aids available is essential. Here, we delve into the options suitable for individuals with sensorineural hearing loss.
When it comes to hearing aids, an audiologist plays a crucial role. They may conduct additional tests like speech tests, tympanometry, electrocochleography, and auditory brainstem response testing to determine the type and severity of hearing loss. The results from these tests, along with an audiogram, can help an audiologist recommend the best hearing solutions for an individual [1].
For sensorineural hearing loss, the main types of hearing aids include Behind-the-Ear (BTE) hearing aids, In-the-Ear (ITE) hearing aids, In-the-Canal (ITC) and Completely-in-Canal (CIC) hearing aids, Implantable Middle Ear Hearing Aids, Bone Conduction Hearing Aids, and Specialty Devices like Directional Spectacles [2].
BTE hearing aids are the most common and versatile option. They rest behind the ear and connect to an earpiece inside the ear canal, making them suitable for various degrees of sensorineural hearing loss [1]. ITE hearing aids, custom-fitted devices sitting in the outer ear, are discreet and suitable for mild to moderate sensorineural hearing loss [1][2]. ITC and CIC hearing aids are smaller, more discreet devices partly or fully sitting within the ear canal, primarily for mild to moderate hearing loss, but their small size may limit advanced features [1].
Implantable Middle Ear Hearing Aids are options for moderate to severe sensorineural hearing loss. These include semi-implantable and fully implantable devices that deliver sound via mechanical vibrations rather than acoustic amplification, differing from traditional hearing aids [5]. Bone Conduction Hearing Aids transmit sound vibrations through the skull bone directly to the inner ear, bypassing the outer and middle ear, and can be considered in some sensorineural loss situations [3]. Specialty devices like Directional Spectacles, hearing aids integrated into eyeglasses frames with directional microphones, are newer and less widely available but represent innovative options for hearing aid users [3].
The choice of hearing aid depends on the severity of sensorineural hearing loss, anatomical considerations, cosmetic preferences, and the need for advanced features. BTE and ITE types are most common for mild to severe cases, while implantable devices are an option for more severe losses or when traditional aids are unsuitable [1][4][5].
Proper assessment and evaluation are crucial for choosing hearing treatment and intervention options. A hearing professional should work with an individual to choose hearing treatment and intervention that is appropriate for their type of hearing loss [6]. The American Speech-Language-Hearing Association warns against using inappropriate over-the-counter hearing aids, as they may worsen hearing loss and cause ear damage [7].
According to the World Health Organization, more than 5% of the world's population need rehabilitation for their disabling hearing loss [8]. If you or someone you know is experiencing hearing loss, it's essential to seek the advice of a hearing professional to determine the best course of action.

- When dealing with sensorineural hearing loss, an audiologist might perform tests like electrocochleography and auditory brainstem response testing to evaluate the hearing loss and recommend appropriate hearing solutions, such as Behind-the-Ear (BTE) hearing aids or Implantable Middle Ear Hearing Aids.
- It's important to consider mental health when dealing with hearing loss, as prolonged hearing difficulties can lead to depression, anxiety, and (social) isolation. The science of health-and-wellness can offer insights into mental health strategies for individuals with hearing loss.
- Specialty devices like Directional Spectacles, hearing aids integrated into eyeglasses frames with directional microphones, are innovative options for hearing aid users, but they are less widely available compared to more traditional Behind-the-Ear (BTE) and In-the-Ear (ITE) hearing aids.
