    How a headphone works. 

    As a audiophile, i have been really interested in how my headphone works. Until recently, i found a video briefly but clearly explained the mechanism behind a headphone. Basically, there are three most important parts. The first one is called diaphragm, which is more commonly known as a column. It is made to pull the air back and forth to create sound. The second and third part are a simple magnet plus a voice coil. When the electricity goes through cable to our magnet, the magnet a electromagnetic field. This field pull the voice coil back and forth, which is attached to the diaphragm, therefore creating sound.

      Hey! I really like the video that you found. With talking about this in class, it can be very confusing but this video gave a better understanding for me. I really enjoyed it. A headphone is so small and intricate and I think we all don’t take into consideration how much effort it takes to produce a small headphone. Now, if only I can find a way to fix my headphones myself without breaking it even more!

    Every year people compete at what can be… 

    Every year, people compete at what can be some of the most ridiculous things in order to otain the title of “Best in the world.” In recent years, the title of fastest guitarest in the world has been traded constantly back and fourth. This is the new fastest guitarest in the world playing the infamous “Flight of the Bumblebee” at speeds of 350 beats per minute. The notes are being played so fast that the merge together we can begin to hear the effects of auditory streaming. https://www.youtube.com/watch?v=zx00BCUqI7U

    I chose to post this video of this guy playing a homemade saxophone. When I first watched this video I closed my eyes and it sounded just like a official saxophone. I found it interesting that this homemade instrument was rather small and it could still make the sound of a normal sized saxophone!

    For my blogpost 5 I thought that I’d share this video, it is a video that shows an original song written with all sounds hit by inanimate objects as the group simply drives along a long path. They have sticks hanging out the windows and doors to hit the objects as they pass them and only the driver is singing.
    I thought this was really fascinating especially as we approach the end of our musical instrument projects.

    Enjoy this unique music video! 🙂

    Amazing Recorder Performance 

    For my musical instrument project, I created a PVC recorder. I based the placement of the recorder’s tone holes off of an old recorder I still had from grade-school. All my life, I have known recorders to be played only by elementary students. It was the instrument that was simple, yet could play “Jingle Bells” for 3rd grade holiday concerts. I wondered what a recorder would sound like if it was played by a professional…It is absolutely amazing. This video is worth watching, or at least listening to! Listening to her play makes me feel as though I’ve been playing wrong for all of these years. If you have ever played the recorder, I’m sure you’ll be amazed with how beautiful one can actually sound.

      I had to play a recorder in 3rd grade and watching this makes me feel very embarrassed for ever having to play in in elementary school. I was so awful. She on the other hand is absolutely amazing the fact that she can make a recorder sound that good is incredible!

    I have been very interested in the vinyl format for a year or two now. In class, we talked about the differences analog and digital formats. This is a video that looks at the advantages and disadvantages of those formats as a play back mechanism as well as a way of recording. Recording a sound using an analog method (tape) will give a much different result than a digital method (computer software). It is a similar effect if you are listening to an analog format like tape or vinyl versus a digital format like mp3.

    Since we’re presenting our homemade instruments this week, I found a tutorial for making your own speakers! It seems pretty easy and cost effective if you have the right tools, and may come in handy someday.

      I also found a tutorial on how to create speakers, but a simpler (if more crude and inefficient) way if you just want to make something quick and easy. Seems like something i might try in the future.

    Since we were talking about speakers and headphones in class, here is a tip to getting the best ones out there. One thing to consider is how accurately the speakers recreate the sound as it was recorded. The most common way to analyse that is by looking at the frequency response spectrum. The flatter the curve, the more accurately it will recreate the sound. Here is the frequency response spectrum of some popular over/on the ear headphones. I’ll leave you with a question… Are Beats by Dre headphones all they are really cracked up to be?

    I enjoyed constructing my instrument and demonstrating it today. Hopefully I got an A.

    The room acoustics of this room causes a greater amount of absorption than we are used to. It’s interesting how our psychological responses cause many different types of responses to being in silence. This person is able to make it an hour, while most cannot stand it past thirty minutes. The heightened senses cause different reactions that are very interesting to observe.

      This is so interesting! I feel like I would get totally creeped out from hearing all my bodily functions. It was crazy how you could literally hear his heartbeat in the microphone too, and how when there were no louder noises the microphone picked up sounds with such low amplitude. Thank you for sharing!
