CAR AUDIO · BLANK RECORD

Noise observation log for a mechanic

Use this page when you already noticed a noise and want a note a mechanic can read. You leave with a blank observation: when it happened, when a similar moment stayed quiet, and the time point in a recording you already have. Download it, copy it, or print it. The page does not find the cause.

Separate what you observed from what you guess. Bring the recording time point you already have.

  1. 1Write down when it happened.
  2. 2Keep what you observed separate from what you guess.
  3. 3Note the conditions when it repeated, and when a similar condition stayed quiet.
  4. 4Hand this note over with the time point in any recording you already have.

Do not fill this in while driving, and do not make a new recording while driving. A repair outcome belongs on a different page and stays out of this observation. This page does not name a part, decide whether the car is safe, or claim the sound will be easier to reproduce.

When this record is not enough

  • You need someone to name a part or decide whether the car is safe to drive. This note does not do that. Take the car to a qualified person.
  • You only have a guess and no observation. Write the guess in the guess field, and leave “What was observed” as unknown rather than filling it with the guess.
  • The job is a setting you changed, or one chosen piece of audio. Those are the tuning log and the listening comparison checklist.

How a filled note can look

Illustrative example — not a real vehicle case

DateExample date only
Existing media file name and time pointexample-clip, about 0:40. Not a real file.
What was observedA short rattle once, remembered after a slow turn. Example only.
Guess, marked as a guessUnknown. The guess field stays empty of a part name.
How often it happenedOnce in this example. Not a pattern.
Speed rangeNot confirmed. Do not invent a speed.
A similar condition when it did not happenA later slow turn with no rattle noted. Example only.
Not yet confirmedWhich part, and whether it will happen again.
Questions for a technicianPlease listen to the existing recording at the noted time point.
Repair outcomeLeft out. This example has no repair and no result.

Questions

Will this page tell me which part is wrong?

No. It is a note for a technician. It does not name a part or a repair.

Should I record a new video while driving?

No. Use a recording you already have. Do not fill this sheet while driving, and do not make a new recording while driving.

Where do I write what the shop did later?

On a separate page. Leave the repair outcome out of this observation so the original note stays what you saw, not what was done afterward.
