Analyse sound levels of different sounds in this room.

Noise pollution has a lot of effects on our health as well as our environment.

17. Home Assignment

shachisehgal — 2015-12-16 17:37:48 UTC

Record sounds of various household appliances and record their characteristics using sensors and list them from low to high

Attach them to Uni note and send it on the class group email.

3. Lets Analyse our voice

Download the App

Sound Waveby Synaptik Tools

The higher the wave form rises , louder the sound and also called the amplitude

2. Physics Note taking

shachisehgal — 2015-12-17 05:22:44 UTC

Uni note for making notes , recording and more

Make a note for todays session.

8. Tuning Fork

shachisehgal — 2015-12-19 10:12:20 UTC

Tuning Forks are used to produce sounds of different frequencies.

A tuning fork is a metal object consisting of two tines capable of vibrating if struck by a rubber hammer or mallet.

1. Sound

shachisehgal — 2015-12-19 14:15:07 UTC

Sound is the term to describe what is heard when sound waves pass through a medium to the ear. All sounds are made by vibrations of molecules through which the sound travels.

7.Sound Sample

4.Sound exploration Lab

shachisehgal — 2015-12-20 11:13:01 UTC

Lets examine some sound samples

5.Sound Sample 1

6.Sound Sample

shachisehgal — 2015-12-20 11:20:52 UTC

9. Frequency means no of vibrations per second. Higher the frequency higher the pitch.

shachisehgal — 2015-12-20 11:51:02 UTC

Look at the diagram.

10.Now lets observe frequency and amplitude of some sound samples

shachisehgal — 2015-12-20 11:53:11 UTC

Download Specosope

12. Activity Time

shachisehgal — 2015-12-20 11:58:00 UTC

Make groups of two

One person will play tones starting from low to high (from Toolbox) Second person will observe the Spectrum using Specospe.

Take a screenshot and post on

10.Ultrasonics and Infrasonics

shachisehgal — 2015-12-20 12:31:33 UTC

Using tone generator ,Press Play button to hear frequencies and slide the dot to increase the frequency.

Which frequencies can you hear?

15.Noise Pollution

shachisehgal — 2015-12-21 07:13:47 UTC

Using Sound Meter App.

Record the sounds being played .

Add the one with highest decibel level on the other padlet

(Attach the recordings to your uni note and send it to the Class Group Mail)
