Traffic noise: results

Trace from experiment 1

Graph showing how sound level varies with noise

This graph shows that there is a direct relationship between road traffic noise and time of day. The sound level is highest on Saturday 29th June.

Road traffic noise

This graph shows the sound level over a 2 minute period. The peaks on the graph are vehicles passing by.

Answers to questions

Experiment 1

  1. (Dependent on your location) In Pico’s experiment it is noisier on Saturday due to the increased number of people going shopping
  2. The noisiest times of the day are 9:00am and 5:00pm as people are travelling to and from work and school at these times. These times are known as the "rush hours"

Experiment 2

  1. In Pico’s experiment approximately 9 vehicles passed by in the 2 minutes the DrDAQ was recording. This is measured by counting the number of peaks shown on the graph above 70 dB. Each peak representing a vehicle passing by

Teachers’ notes

Safety notice: children must be well supervised and briefed on road safety if experimenting near roads. These experiments should preferably be done by suspending the DrDAQ unit out of a building window that faces a road.

Testimonials

  • I have been using my 4224 PicoScope for years. I travel abroad so this has been ideal due to its physical size. Storage of waveforms on my Laptop is very easy allowing me to quickly email waveforms to my Colleagues.

    Andrew
  • Not many USB scopes works on Win & Mac & Linux too, so that proves me that guys from Pico really cares about us, customers. This made my decision much easier when I was looking to buy an USB scope.

    Raul Trifan
  • We have been using Picoscope 6404D for quite some time, and are amazed by its accuracy and powerful emulations while working with numerous signal evaluations.

    J Mohanty
  • PicoLog TC-08: This is a very nice unit that works consistently and reliably.

    Jeff Hulett
  • It is a great scope. I had a weird problem - it did not work on one of my PC’s. Customer service gave me first class service. If I could give 6 stars for customer service - I would do so.

    Niels Larsen
  • Perfect Partner for Development of Encoder controlled Stepper Motor Actuators. Since the included software is really stable, this type of device is a great tool for great tasks!

    Helmut Schoettner
  • A superb piece of equipment worth its weight in gold

    Nigel Clinch
  • So simple to use & beats any other I have ever used hands down.

    John D Samsing
  • Great functionality in a compact size. I really like moving the mouse pointer to a position and having the Time and Voltage display the values at that point. Calibration equipment is a breeze with that feature.
