Tuning Fork Interpretation With a 512 Hz Fork: Weber Heard in the Right Ear, Bone Conduction Outlasting Air on the Right Only, and Why the Pattern Fits the Fluid Seen Last Week
Instrument and Setting
Fork: 512 Hz, struck on the examiner's knee to a moderate loudness, not on a hard surface. Room: a closed exam room with the ventilation fan off. T.M. was asked to report where the sound was heard and when it stopped, and the examiner timed both with a watch. Each test was repeated once to confirm the response.
Both Tests, Both Sides
Table 1
Tuning Fork Results Recorded by Ear
| Test | Right ear | Left ear |
|---|---|---|
| Weber, fork on midline forehead | Sound heard louder in the right ear | Not heard louder on the left |
| Rinne, bone then air | Bone conduction heard longer than air (about 14 seconds on bone, then not heard at the canal opening) | Air conduction heard longer than bone (about 12 seconds on bone, then a further 9 seconds at the canal) |
Note. Note. Times are approximate and were taken with a watch; each response was confirmed on a second strike.
Which Conduction Lasted Longer
On the left, sound carried through air outlasted sound carried through bone. That is the normal relationship, because the middle ear amplifies sound reaching it through the canal. On the right, the relationship was reversed: once the fork was moved from the mastoid to the canal opening, T.M. could not hear it at all. When bone outlasts air on one side, sound is being blocked on its way through the canal or middle ear.
The Pattern, Read Out
Weber lateralizing to the right and right-sided bone conduction outlasting air together point to a conductive hearing loss in the right ear. With a sensorineural loss in the right ear, Weber would have lateralized to the left, the better cochlea, and Rinne on the right would still show air longer than bone. The sudden hearing loss guideline recommends that clinicians separate conductive from sensorineural loss at the first visit, and tuning forks are one of the ways it lists to start doing so (Chandrasekhar et al., 2019). The pattern also fits last week's findings: a right middle ear filled with fluid blocks air-conducted sound and leaves bone conduction intact.
When Results Disagree
They did not disagree here, but they could have. A Weber that stayed in the midline with a reversed Rinne on one side would have needed repeating, because a small conductive loss may not lateralize. A Rinne that changed between the two strikes would have been recorded as inconsistent rather than averaged. Results that conflict with the otoscope findings are written down as conflicting and sent for audiometry, not resolved on paper.
Where the Fork Stops
A tuning fork gives a direction, not a measurement. It cannot say how many decibels are lost, whether there is a small sensorineural component on the same side or how the left ear compares with normal at other frequencies. Bickley et al. (2021) describe the Weber and Rinne tests as screening tools that should be followed by audiometry when a loss is found. T.M. was referred for pure-tone audiometry and tympanometry, which will measure the loss and the drum's stiffness.
How the Result Was Explained to T.M.
T.M. asked whether the hearing would come back. The answer given was that the test pointed to sound being blocked on its way in, most likely by the fluid seen behind the right drum, rather than to damage in the inner ear or the nerve, and that this kind of loss often improves when the fluid clears. T.M. was also told that the clinic could not yet say why the fluid had stayed for so long in one ear, and that the hearing test and a later look at the back of the nose might be needed to answer that. T.M. agreed to the audiometry appointment and was asked to report any spinning, ringing or sudden worsening of hearing before then, because those would change the urgency.

PA 516 Week 3 instructions, in plain terms
For the third week you interpret tuning fork tests from a case. Name the fork's frequency and how it was struck, and describe the room, since noise and a hard strike both distort results. Record Weber and both Rinne tests in a small table or labeled lines, with the side for each. Write each Rinne result as which conduction lasted longer, with times if you have them, because positive and negative mean opposite things in different books. Then read the pattern aloud: what the combination says about conductive or sensorineural loss and on which side. Explain what the opposite pattern would have looked like. Say what you would do if the tests conflicted with each other or with the otoscope. Close with what a fork cannot tell you and the test that can.
Inside the PA 516 Week 3 example
The paper opens with a 512 Hz fork struck on the knee in a quiet room, with each response timed and repeated. Table 1 records Weber heard in the right ear, bone outlasting air on the right at about 14 seconds and air outlasting bone on the left. A section explains why air normally lasts longer and what reversal means. The pattern is read as a right conductive loss, contrasted with the left-lateralizing Weber a right sensorineural loss would produce, and tied to last week's fluid. The sudden hearing loss guideline is cited for separating conductive from sensorineural loss early. A conflict section explains how mixed results would be recorded. The limits section cites Bates' guide on forks as screening tools, and a final section explains the result to T.M. and books audiometry and tympanometry.
Where the points sit in the PA 516 Week 3 rubric
Faculty grade this interpretation mainly on whether the pattern is read correctly and explained. Mixing up which ear Weber lateralizes to in a conductive versus sensorineural loss is the costliest error. Close behind is a Rinne written only as positive or negative with no statement of which conduction lasted longer, since the reader cannot verify it. Credit grows when both sides are recorded for both tests and the frequency of the fork is stated. Explaining the alternative pattern earns marks because it proves the reasoning works in both directions. Deductions apply to interpretation that runs past the evidence, such as naming a decibel level or a final diagnosis from a fork alone. The final section should name the confirming test, and references should support any claim about how the tests are used.
PA 516 Week 3 help from the desk
A frequent problem with this assignment is labeling results without explaining what they mean. Send your Weber and Rinne findings, the fork used and the otoscope result from your case, and the custom sample will put the results in a table by ear, write each Rinne as a comparison and read the combined pattern. It will also show what the opposite pattern would look like for your scenario, which is the part many drafts leave out. If your results are mixed or inconsistent, the sample shows how to record that honestly rather than forcing a conclusion. The limits section names the follow-up test your program expects. Check the side and the times against your own notes before you use any of the wording in your submission.

PA 516 Week 3 questions, answered
Do I need to name the fork's frequency?
Most rubrics carry a row for method and the frequency is the cheapest part of it. Finished examples name the fork, say where it was placed for each test, and state what the patient was asked to report. Leaving those out turns three results into three assertions, and a grader checking method against findings has nothing to tick in the first column.
Is a table better than paragraphs?
For this week, generally yes, and several sections require one. Three results across two ears read as a pattern when they sit in a grid and dissolve when they are written as sentences. Where your classroom asks for narrative, the finished version keeps one result per line so the comparison survives. Send the instructions and the example follows the required form.
How far should the interpretation go?
As far as a category and a side, and no further. The graded claim is that a pattern is consistent with a conductive or a sensorineural loss in a named ear. Naming a specific condition, or moving on to what ought to be done about it, reaches past what two fork tests support and past what the week is marking.
