13. Reread the text and mark the following statements as “true”, “false” or “no information”:

 

True False NI

1. The term “acoustics” had received a broader meaning long before the terms

“ultrasonic” and “infrasonic” appeared.

2. Putting into practice the noise control technology has similar characteristics in

indoor and outdoor environments.

 

Ultrasonic sound waves are beyond the human hearing.

 

Room acoustics describes how sound behaves in an enclosed space.

 

Sonar is the most important application of ultrasonics.

 

It is impossible to simulate ideal sound wave behaviours.

 

Reverberation is outside the scope of basic sound wave behaviours.

 

The loss of energy due to sound wave reflection is referred to as absorption.

 

Mathematical analysis turns out to be the most complicated procedure of sound control.

 

10. Hydroacoustics is in charge of monitoring underwater physical properties.

15. Look at the mind-map in Ex.15 again. Work with a partner and describe acoustics and acoustical engineering basics in your own words. Use the following discourse markers to help you:
