    Hearing Aids...

    • Stimulate the hearing nerves

    • Increase the volume of sounds

    • Change the frequencies of sounds

    Correct Answer
    A. Increase the volume of sounds
    Explanation
    Hearing aids are devices designed to help individuals with hearing loss by amplifying sounds. They work by increasing the volume of sounds, making them louder and more audible to the wearer. This helps individuals with hearing loss to hear sounds that they may not have been able to hear otherwise. By increasing the volume of sounds, hearing aids can improve the overall quality of life for individuals with hearing loss.

    Which is not part of a hearing aid?

    • Amplifier

    • Microphone

    • Electrode Array

    • Speaker

    Correct Answer
    A. Electrode Array
    Explanation
    An electrode array is not part of a hearing aid. A hearing aid typically consists of an amplifier, microphone, and speaker. The amplifier increases the volume of sound, the microphone picks up sound, and the speaker delivers the amplified sound to the user's ear. However, an electrode array is not used in hearing aids. It is commonly used in cochlear implants, which are different devices used to help individuals with severe hearing loss or deafness.

  • 4. 

    Which isn't a type of hearing aid?

    • Canal Aid

    • Behind the Ear Aid

    • Ear Drum Aid

    • In the Ear Aid

    Correct Answer
    A. Ear Drum Aid
    Explanation
    The correct answer is "Ear Drum Aid" because it is not a type of hearing aid. The other options listed - Canal Aid, Behind the Ear Aid, and In the Ear Aid - are all types of hearing aids that are designed to assist individuals with hearing loss. However, an "Ear Drum Aid" is not a commonly recognized type of hearing aid. It is possible that this option was included to confuse or mislead the reader.

    Rate this question:

  • 5. 

    Which type of hearing loss are cochlear implants for?

    • Mild to moderate conductive hearing loss

    • Mild to moderate sensorineural loss

    • Severe conductive hearing loss

    • Severe sensorineural loss

    Correct Answer
    A. Severe sensorineural loss
    Explanation
    Cochlear implants are designed for individuals with severe sensorineural hearing loss. Sensorineural hearing loss occurs when there is damage to the inner ear or the auditory nerve, making it difficult for sound to reach the brain. Cochlear implants bypass the damaged parts of the ear and directly stimulate the auditory nerve, allowing individuals with severe sensorineural hearing loss to perceive sound. Cochlear implants are not typically used for mild to moderate hearing loss or conductive hearing loss, as these conditions can often be managed with other forms of treatment such as hearing aids or medical interventions.

    True or False: Hearing aids don't need to be tailor-made, but cochlear implants do.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Both need to be individually tailored

    Rate this question:

  • 7. 

    Which is not part of a cochlear implant?

    • Amplifier

    • Electrode Array

    • Transmitter

    • Speech Processor

    • Microphone

    Correct Answer
    A. Amplifier
    Explanation
    An amplifier is not part of a cochlear implant. A cochlear implant is a device that helps individuals with severe hearing loss by bypassing the damaged parts of the ear and directly stimulating the auditory nerve. The main components of a cochlear implant include the electrode array, transmitter, speech processor, and microphone. The electrode array is inserted into the cochlea to stimulate the auditory nerve, the transmitter receives and processes sound signals, the speech processor converts sound into electrical signals, and the microphone picks up sound from the environment. However, an amplifier is not necessary as the transmitter and speech processor already perform the amplification function.

    Rate this question:

  • 8. 

    What type of cells does the electrode array stimulate? 

    • Hearing cells

    • Hair cells

    • Auditory cells

    • Cochlear cells

    Correct Answer
    A. Hair cells
    Explanation
    The electrode array stimulates hair cells. Hair cells are sensory cells found in the cochlea of the inner ear and are responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. By stimulating these hair cells, the electrode array can help individuals with hearing loss to perceive sound.

    In a cochlear implant, the __________ determins the pitch or frequency, while the amount of current determins the loudness

    Correct Answer
    position
    location
    Explanation
    In a cochlear implant, the position of the electrode array inside the cochlea determines the pitch or frequency of the sound that is perceived. The electrode array stimulates different regions of the cochlea based on their position, allowing the brain to perceive different pitches. On the other hand, the amount of current delivered through the electrode array determines the loudness of the sound perceived by the individual. By adjusting the current level, the loudness of the sound can be increased or decreased.

    Which parts of the cochlear implant are surgically implanted?

    • Transmitter

    • Receiver

    • Microphone

    • Speech processor

    • Electrode array

    Correct Answer(s)
    A. Receiver
    A. Electrode array
    Explanation
    The cochlear implant is a device that helps individuals with severe hearing loss. It consists of several components, but only the receiver and electrode array are surgically implanted. The receiver is placed under the skin behind the ear, while the electrode array is inserted into the cochlea. The receiver picks up signals from the external components of the implant and sends them to the electrode array, which stimulates the auditory nerve, allowing the person to perceive sound. The microphone and speech processor are external components that capture and process sound before transmitting it to the implanted parts.
