Read again the text and write (T) for True or (F)
for False.
Writing: work in pairs and try to find what kind of
similarities there are between hearing aids and microphones.
1. Microphones are electronic devices which boost the voltage,
current or power of a signal.
2. Amplifiers don’t convert sound energy to elecrical energy.
3. The permanent magnet collects the sound waves.
4. So few people are aware of the way the microphones work
In my opinion, they help us hear the sounds around us more clearly. Both
have an electronic mechanism which amplifies the sounds coming from the
environment. ……………………………………………………………………………….
