Thank you for this amazing explanation. This video has given me a good understanding on the concept. However, I have two questions. 1) Assume that the air pressure at a particular place is higher than normal. Will the sound wave travel faster or slower than normal there? 2) Assume that at an atmospheric temperature and pressure of 20 C and 1 atm, two persons are conversing with each other. One person is speaking softly and the other person is speaking loudly. Will the speed of the sound from both the persons be same or vary with loudness? Thanks
Satish Natarajan Thanks for your questions. Here's our best answers to your questions .. 1) Speed of sound is normally measured with reference to wavelength. Because a single cycle (wavelength) contains both high pressure (compression) and low pressure (rarefaction) we would say that there is no difference in the speed of the wave at compression and rarefaction. 2) Well now you're talking physics! :-) which is beyond our expertise (we're humble music technologists!), but speed of sound is not dependant on amplitude. However it is dependant on factors that affect the medium through which it is travelling (propagating) so density, temperature and altitude can effect it. Hope this helps.
+Lunar Rising Well thanks! We never know how clear our videos are and always think wonder if we cold have made them better so its good to hear they are useful.
I understood thanks. But how sound can be transmitted with help of molecules if they're not stationary and flying around the room with very high speeds?
Thanks for your comment. It's important to understand that the air molecules are not flying around a room, but that each is vibrating around a fixed point. They hit each other in a chain reaction thereby transferring the sound wave energy. Hope this helps.
It's important to recognise that sound is not mass, or matter. It is energy, and in the case of air molecules a function of their vibration. So sound is energy that propagates through a medium. We are not aware how brownian motion relates to sound theory in a project studio, but the general concepts of diffusion will be covered in a future video series on reverberation.
Man you explain complex things so simply. I can see clearly how a room acoustics plays a huge role.
Glad you're finding the videos useful Cali. Thanks.
This is one of the most easiest & well made video/ tutorial i have seen on 'Sound'.. Subscribed :-)
Thanks Sharanya.
Best explanation and visualization of sound theory ever.
Thanks Naif.

WOW! this videos is amazing!

+Project studio handbook thanks for you guys my homework became easy

but what about ... Brownian motion.. and diffusion

sound is light that we hear lol
