Panasonic Lumix DMC TZ7/ZS3 Sound Test
Noise Study: Zoom/Autofocus Noise v1 [720P]

Noise Study: Zoom / Autofocus (Informal)

Conditions: Quite {Quiet} Room
Post Processing:
Part 1: Normal Audio
Part 2: Audio Enhanced by 12db
Date: March 4, 2010

Clip Sequence:

1. Room Ambiance
2. Zoom Starts
3. Zoom Stops
4. Room Ambiance

The clips are played back in various manners to illustrate the entire spectrum of noise generated by the zoom motor in the camera.

There are two parts. Part 1 plays back the clip(s) with no audio enhancement, dragged strait to the timeline.

Because the audio may be too low to here on normal computer speakers, Part 2 repeats the clip sequence with a 12 db enhancement to the audio track.

Notes:
1. Enhancing audio level by 12db equally
enhances the ambiance as well.
2. This was done for practical reasons
for playback on regular speakers.
3. Zoom lever release noise remarkable.
4. Zoom noise may be drowned out by
traditional outdoor ambiance.
5. Zoom noise may be noticable under quiet
conditions such as a personal one-on-one
interview, or other quiet room setting.

Corrections:
1. Spelling error in opening title where "Quite" Room, should be "Quiet" Room. (Rev. 03/21/10 08:30).
