Flashcards
Pitch
Pitch
The frequency of sound waves, measured in Hertz (Hz). Higher frequency means higher pitch.
Intensity (Loudness)
Intensity (Loudness)
The amplitude of sound waves, measured in decibels (dB). Larger amplitude means louder sound.
Rinne Test
Rinne Test
A hearing test that compares bone conduction (sound through bone) to air conduction (sound through air) to differentiate between conductive and sensorineural hearing loss.

Study Notes
1.3 One Page Wonder: Aids/Cochlear Implants
- Aids help/cochlear implants assist individuals with hearing loss.
- Sound waves vibrate at different frequencies (measured in Hertz).
- Higher frequency corresponds to a higher pitch.
- Sound intensity (loudness) is measured in decibels (dB).
- Greater amplitude results in a louder sound.
- Hearing tests (Rinne, speech in noise) evaluate different aspects of hearing.
- Pure tone tests determine frequency ranges of hearing.
1.3.1 Physics of Sound
- Pitch refers to the frequency of sound waves, measured in Hertz (Hz).
- Higher frequencies result in higher pitches.
- Intensity (loudness) relates to the amount of energy in sound waves, measured in decibels (dB).
- Louder sounds have greater amplitudes.
1.3.2 Hearing Tests
- Rinne Test: Measures bone and air conduction; compares the duration of sound heard through bone vs. air conduction to identify conductive hearing loss. If bone conduction is longer, it suggests a conductive hearing loss. If air conduction is longer it can suggest a sensorineural hearing loss.
- Speech in Noise Test: Assesses the ability to hear speech in noisy environments.
- Audiograms: Visual representation of hearing thresholds or ranges.
- Normal hearing thresholds on an audiogram are similar for bone and air conduction.
- Hearing loss severity can be categorized by decibel ranges like mild (21-40), moderate (41-70), and severe (71-90).
1.3.3 Cochlear Implants
- Mechanism: Cochlear implants translate sounds into digital codes. A sound processor converts the sound into electrical signals. The signals stimulate the auditory nerve, transmitting sound.
- Pros:
- Improved hearing compared to hearing aids for some with moderate to severe hearing loss.
- Enhanced ability to hear important sounds in noisy environments.
- Improved ability to focus.
- Cons:
- Potential for a negative impact on the Deaf community's sense of identity and culture
- Reduced or eliminated access to Deaf culture if many choose to use cochlear implants.
- Some individuals, notably the elderly, might not achieve the same benefit with efficacy.
