Question

can the sound travel on thread ​

Answer 1

Answer:

You can hear surprisingly far using a thread telephone if help the right way!

If the thread is kept tight, the sound waves will travel. If the thread is loose, the sound is less. This is because the lose thread causes the vibrations to travel all around rather than directly down the thread.

Answer 2

Answer:

Yes, if the thread is kept tight. There will be less sound if it is loose.
