DHA Audiologist - Exam Topics Sample Questions

What does otitis media typically cause?

Correct Answer:
it causes conductive hearing loss.


otitis media primarily causes conductive hearing loss. this condition is an inflammation or infection of the middle ear, which is the air-filled space behind the eardrum that contains the tiny vibrating bones of the ear. children are more commonly affected by otitis media due to the structure of their eustachian tubes being shorter and more horizontal, which can make it easier for pathogens to access the middle ear.

conductive hearing loss occurs when there is a problem conducting sound waves anywhere along the route through the outer ear, tympanic membrane (eardrum), or middle ear (ossicles). in the case of otitis media, fluid buildup in the middle ear, a common symptom of the infection, can prevent the ossicles from moving freely. since these bones need to vibrate in order to transmit sound from the air to the cochlea (the sensory organ of hearing), any restriction in their movement can lead to diminished hearing.

while otitis media is specifically an issue with the middle ear, it does not typically cause sensorineural hearing loss, which affects the inner ear or the neural pathways to the brain. nor does it usually cause mixed hearing loss, which is a combination of conductive and sensorineural hearing loss. however, in severe or untreated cases, the infection can potentially spread to the inner ear or lead to more serious complications that might affect both the conductive and sensorineural components of the auditory system.

in conclusion, otitis media most commonly leads to conductive hearing loss due to the accumulation of fluid in the middle ear, which impedes the proper transmission of sound through the middle ear. regular medical attention and treatment are essential to prevent the condition from leading to more significant hearing impairment or other complications.

Using the Lexical Neighborhood Test, which of the following is an "easy" word?

Correct Answer:
juice.
to answer the question about which word is "easy" according to the lexical neighborhood test (lnt), first, we need to understand what the lnt entails. the lexical neighborhood test is a measurement used in psycholinguistics to assess word recognition and auditory perception. it evaluates how easily a word can be recognized in relation to how many similar sounding words (neighbors) it has. a key aspect of the lnt is that "easy" words are those with few neighbors, making them less likely to be confused with other words. in the given list of words—juice, thumb, pie, wet, fight—we need to determine which word has fewer phonetic neighbors.

**juice** - the word "juice" has several phonetic neighbors like "choose," "juke," etc., which makes it more challenging to recognize distinctly in a noisy environment.

**thumb** - "thumb" also has neighbors such as "dumb" and "numb." however, it has fewer neighbors compared to "juice."

**pie** - "pie" has a very straightforward and distinct sound with very few neighbors such as "tie," "buy." it likely stands out clearly.

**wet** - similar to "pie," "wet" has a distinctive sound but with possible neighbors like "vet," "bet," and "set."

**fight** - "fight" has neighbors including "light," "right," and "sight," which might make it more challenging to recognize due to the higher number of similar sounding words. based on this analysis, the words **"pie"** and **"wet"** are likely the easiest among the list as per the lexical neighborhood test because they have fewer neighbors, making them less susceptible to confusion with other words. between "pie" and "wet," "pie" might be considered easier due to its very distinct and short phonetic structure, making it less likely to be confused with other words. hence, "pie" is the "easy" word according to the lexical neighborhood test criteria provided in the question.
