Download the Praat (Free acoustic software) from https://www.fon.hum.uva.nl/praat/Links to an external site.

Create the waves with the parameters (duration 4 seconds) below with the Praat

Wave 1: amplitude 0.2 pa, frequency = 250 Hz

Wave 2: amplitude 0.2 pa, frequency = 500 Hz

Wave 3: amplitude 0.2 pa, frequency = 1000 Hz

Wave 4: amplitude 0.4 pa, frequency = 1000 Hz

Listen to these wave audios and answer the following questions:

Questions:

1. What are the periods of Wave 1, 2, & 3?

2. What's the relationship between Wave 1, 2, and 3?

3. What are the perceptual differences between Wave 1, 2, and 3?

4. What is the acoustical difference between Wave 3 and 4?

5. What is the perceptual difference between Wave 3 and 4?

6. What are the intensities in dB of Wave 3 and 4? (Formulas and calculation steps are required)
