Good morning! I have finally finished up the pdf of Yiruto!

My video and sound files are all here.

Sound Texturizer : YIRUTO

This assignment we are tasked to make a product that produce 3 sound qualities.

I just knew this is my chance to explore magnets. I don’t know how i’m gonna make sound with it but magnets will be my main medium.

 

This is my initial draft sketch before exploring online.

Upon researching, i found this really cool video and that’s where my source of inspiration come about.

 

I tried making it but failed. I couldn’t make the CD spin continuously and have that “free energy” flowing through it. Mine is like a spoiled old car that spin only a bit then pause. Spin, pause, spin pause. Even when i increased the amount of magnets, it still the same. Probably spin just a bit more only haha.

 

I explored a lighter material using plastic container lid and bottom. Using the middle one in the photo give a better result. As the container bottom is lighter and has a smooth protruded center, it aids in the spinning, making it turn longer. Although there is still pauses in between, this is the best i could go for.

 

 

 

I had various ideas to make use of the spinning motion. I could make it like a swing ride, have something attached to the base, so when they collide, they would produce sound in a way like wind chime. I also thought of adding bristles along the side of the rotating disc, the bristles will brush along the edge of the container and produce sound. Basically there will be layers of different sounds.

 

 

When i went to art friend, i saw this interesting globe ball that can be separated into half. I thought it would be fun to test it out like a roly poly toy. With this new toy, i thought of various ideas like having a slide circulating the globe. Thus, when the rotating disc hit at certain point, there will be a mechanism that release a ball and it would slide down the slide, producing an echo and Doppler effect. However i feel that this is too time-consuming when i had other assignments to do too. Hence i decided to create different layers of sound instead.

 

I explored with different materials and textures to see which give the result i wanted.

 

I wanted sounds that goes well with each other and create a sci-fi music like at 6:48-7:00.

 

 

This is my first prototype which i presented in class.

 

Lots of layers inside.

 

Now let’s hear the sound individually in each layers.

 

First up is the capsule that contains a bead and a decorative piece.

 

Secondly is the capsule rolling around on very crumpled aluminium foil.

I made the shadow of “Ben” Grimm’s face! So cool!

 

 

Thirdly is a smoother surface of aluminium foil.

 

 

Lastly, is the beads circulating in the slightly rubbery lid.

 

 

This is what the capsule sound like without any foils.

 

 

Comments from Mrs Cherly: The sounds are very delicate. Maybe can try to extrude out the lid using wire mesh, so the sounds can project out.

 

Personally, i like soft low pitch sounds. However i feel that my sounds doesn’t have a clear distinct separation with each other because they are all trapped under the thick cardboard lid, a poor conductor of sound. After seeing the class presentation, i realized i should make my sounds louder. Hence off to the next prototype.

 

 

Following Mrs Cherly’s advice, i changed the material of lid to a thinner cardboard and extrude it out. I feel that changing into a thinner layer of material has the same effect as protruding out the lid. Hence i decided to go with a thinner layer instead. Ultimately, i choose a pvc sheet so that the inner layers could be seen as well.

 

Besides playing around with different textures of foil, i also tried experimenting with different beads.

They look so pretty together! It look like i’m doing jewelry photography. 

 

 

With this i created a new planet, Yiruto! The tiniest, noisiest planet the mankind ever discover on this universe!

 

Rolling the bell on foil.

 

Rolling the bell on foil in bowl container.

 

Beads and decorative “stars” on top of a rubber lid in a bowl container. Occasionally the metallic beads will bounce up and come in contact with the container and circulate on top of the lid. The friction between the container with the bead produce a unique vibrating high pitch sound.

 

 

 

Witness Yiruto’s Revolving Moments!

 

 

 

After a final consultation with Mrs Cherly, She advised me to lift up the foil a bit so there’s room for the bead to circulate.

 

 

 

 

How a metallic bead sound make a difference.

 

 

Upgrade Version of Yiruto in Action

 

 

 

 

 

Special video!

 

When testing out different bells, i realized some bells are conductor of magnets. This is the strongest among all the bells i tested. There’s a whole new approach of making sound in this video.

 

 

Personally, i like the sound of the first version of Yiruto. The chiming bell sound is louder and create a beautiful sound with some occasionally vibrating beads. Then again, the second version fit my sci-fi theme better. Although i feel that the echoy sound could be better improve to fit my theme.

Sound Conductors

Sound waves travel faster through denser medium. That’s why sound travel faster in water than air. But even more influential than a conducting medium’s density is its elasticity. Elasticity refers to how well a medium can return to its initial form after being disturbed by a force. Steel has high elasticity. It bounces right back to its original shape after an applied force is removed. At the particle level, the molecules in elastic materials transfer energy more efficiently, so sound waves travel faster through steel than through water or air.

I found this video pretty cool. We can play different instruments through air.

 

Euterpe

euterpe-18

She is the daughters of Mnemosyne and is called the “Giver of delight”. In late Classical times she was named muse of lyric poetry and depicted holding a flute.

 

Destructive Interference

constructive-destructive-interference-results

When the crests or troughs of two interfering waves meet, their amplitudes add together. This principle is known as constructive interference. When the opposite happens, and it’s called destructive interference. When the crest and trough of two interfering waves meet, one amplitude subtracts from the other.

 

This is how a tuning fork works.The piano tuner strikes the tuning fork, and at the same time strikes the appropriate key on the piano. If their frequencies are perfectly aligned, so is the sound of both; but, more likely, there will be interference, both constructive and destructive. In the case of constructive interference, their combined sound will become louder than the individual sounds of either; and when the interference is destructive, the sound of both together will be softer than that produced by either the fork or the key.

Anechoic Chamber

It is the most quietest room in the world designed to completely absorb reflections of either sound or electromagnetic waves. They are also insulated from exterior sources of noise. I wish i can go inside to hear my blood flowing and what sound my body make.

White noise

It is random signal having equal intensity at different frequencies, giving it a constant power spectral density.

 

Refraction

refr2

Refraction is the bending of waves when they enter a medium where their speed is different. The different of temperature in water also cause refraction. This seem interesting to work with.

Research: Sense of Hearing

How do we hear?

 

Imprimir

 

The human ear is divided into 3 parts such as the outer ear, the middle ear and the inner ear. The outer ear is comprised of the auricle and the ear canal. They channel sound waves toward the eardrum. The eardrum passes along the sound vibrations to the ‘ossicles’, the three smallest bones in the human body, then divert it to the fluid-filled, ‘labyrinth’-like structure in the inner ear called the ‘cochlea’, where the true hearing organs reside. The sensory organ for hearing is the “Organ of Corti” containing about 15,000-20,000 specialized sensory cells, each with a tiny hair capable of picking up minute vibrations in the cochlear fluid.  Various hairs are specialized to detect sounds at various frequencies, and turn them into nerve signals to be sent to the brain.

It interesting to see how our ears operate like various instruments put together to produce music in our brain. With the ear drum taking on the drum role, the ossicles on the tuning fork and the hairs inside the cochlea is the shaker. Its lacking a ukulele to make a chill hipster band.

 

Ear Pressure

Sometimes our ears are blocked when we are ascending up in the sky on the airplane or diving underwater. It is caused by the change of barometer pressure in the Eustachian Tube. The Eustachian tube connects the middle ear to the back of the nose. This tube opens and closes while we swallow or yawn. This movement helps equalize the pressure between the middle ear and the outside environment. If it does not work properly, negative pressure develops in the middle ear leading to ear problems  like a blocked ear. When this happen, we can try to yawn to open the tube.

 

HOW IS FROG SIMILAR TO HUMAN?

green-frog-mouth-wide-open

Cheryl post this question to us and im quite amazed at my findings with this cute little creature.

 

  • Same Organs

Both frogs and humans have many of the same organs. Frogs and humans have lungs, stomachs, a heart, a brain and livers.

  • Similar Skeleton Construction

Just like in a person’s arms, in a frog’s front legs are bones called the humerus, the radius and the ulna. They have 5 fingers and toes like us too.

  • Hearing Mechanism

They do have eardrums and an inner ear like us. The frog ear is called a tympanum and the size of the tympanum and the distance between them are relative to the frequency and wavelength of the species male call. Their eardrum works like a regular eardrum with one very special adaptation…it is actually connected to their lungs. The lungs vibrate and are almost as sensitive to hearing as the eardrum. This allows frogs to make really loud sounds without hurting their own eardrums!

 

Bizarre Facts

  • In the early 20th century biologists discovered that African clawed frogs were unusually sensitive to human chorionic gonadotropin (HCG), a hormone produced by pregnant women. Doctors would inject a frog with a woman’s urine, and if she was pregnant, the frog would ovulate and produce eggs in 8 to 10 hours.

  • Frogs use their eyeballs to swallow. Frogs eat their prey whole and their eyeballs actually sink down into their mouth and push the food down into their throat.

Yucks! I can’t look at them in the eye now.
