Beats Demo: Tuning Forks

This is a demonstration of the periodic variations in the sound loudness, or "beats," produced by two frequencies that are close to each other, with the beat frequency given by the difference between these frequencies. The nearer the two frequencies, the slower the beats. Thus, musicians "tune out the beats" to tune their instruments to a reference frequency.

It was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

thanks, I studied theories about it but never saw practically... thank you very much.

`Wow. wow' What an explanation!..

[timpaulson]

Thanks for making all these demo videos, with my classes out due to corona and no access to my equipment, your videos have helped bring physics to life to my students.

My sir(MR Sir PW) used this vdo to visualize beats frequency... Thanks❤

[YtheMissingH]

Nice explanation..I finally understood beat is actually the waau-waau sound...and your necktie is the pattern of piano keys. Wow!

[yeahwhatever.]

Yes I'm here after MR sir's wave lecture😂✋ also this demo is superb! Thanks a lot

[AbishkarAK]

thanks a lot for the demonstration. In our school, we are barely shown such demonstrations and i think these demonstrations are absolutely required for learning physics.

I'm a mechanical engineer and I've heard this many times being in India. When temple bells ring, I've noticed this a lot and have wondered what was that wahwahwahwah sound !


And here I get an answer, just amazing. No f**king teacher (not being disrespectful but just an emotional thing), all my life taught me behaviour of Beats phenomenon in real life.

I bow to you!

[iamhe-man]

It feels amazing when you experience the theory in practical form thank you so much ❤️🙏

[RaviKumar-ovnl]

Do you hear the wa wa wa?
Me: yes of course, you're doing it.😂

[fakhrizalarsi]

wow wow wow wow... wow wow. It's super easy to understand, barely an inconvenience!

[iknowsomestuff]

I have never see a tuning fork so I Needed this to understand my textbook . This was nice . Especially the piano tie .

[omega]

Such a beautiful demonstration. I look forward to more <3

[drbijapur]

Thank you sir..I appreciate your work for making students understand concepts practically.

[MNGN]

I have my physics exam tomorrow and i didn't understand beats in waves until now. Thank you very much sir!

[shoniziawazir]

Absolutely confusion crusher sir.Teacher is the outstanding welwisher and nation builder and worthier of thanks

[pratyushsingh]

beautiful demo fs

(love your tie prof)

[Medjourney]

Hey, I am from physicswallah, after lecture of beat formation to see demo of it.
And I got perfect explanation and demo,
Thanks
😍😍😍

Thanks, I sent this to a non-musician who has just joined the church choir club and wants to know how to tell when something or someone is in tune.

[mohamedrabie]

love how he matches his tie with the topic <3
