CT1_Noise_and_Luminosity_Research

To measure noise and luminosity we walked our path on cold day of 30th December 2010. The picture from endomondo website (below) show our route registered by GPS:

Noise

Methodology

To measure noise we used Iphone with Decibel application. We took measurements in 11 point of route. Application we used showed 3 different values of sound in dB: average level, peak level, maximum level. Detailed description on picture below.



Results

Here are results that we obtained:

Noise level results table


Noise level results chart

Loudest point: #2: Constitusions square (average sound level: 93 dB)

Quietest point: #9: Złote Tarasy shopping center (average sound level: 61 dB)


Common noise levels for comparision:

  • 40-50 dB: quiet bedroom
  • 50-60 dB: private office
  • 55-65 dB: open office space
  • 60-70dB: conversation from 1m distance

Luminosity

Methodology

To measure luminosity we used a camera with fixed settings. It allowed us to obtain comparable frames from key points of our route. Pictures were made from the same height (eye level) with axis of the lens parallel to ground.

Camera settings:

  • Film Speed: ISO 200
  • Aperture: f/ 2.8,
  • Shutter speed: 1/250s
Camera settings

Results

As a result we got 11 pictures one from every point.

To get comparable number values of luminosity from these pictures we exported gray values of every picture (using Adobe Photoshop).


Here are the values:




The most interesting parameter that represents luminosity (brightness of the picture) is mean gray value of the picture.

Darkest point: #10 Warsaw Central Railway Station

Brightest point: #2 Constitutions Square
