Longitudinal Sounds

A sound wave is a disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transfer of matter. In Activity 2 on page 8 we had to model sound waves using an instrument. In our class we used a flute as the example and when the person blew into it, sound waves were produced. As they blew and changed the volume and pitch the sound waves changed. A sound wave is created when something vibrates. When something vibrates, longitudinal waves are created which we can hear. A longitudinal wave is a wave that transfers energy through compressions and rarefactions in the material that the wave travels which are all parts of a sound wave. In Activity 2 it states in some parts of the wave, the air molecules

When a person with normal hearing hears the sound travels along the ear then bounces against the ear drum. The eardrum, the bones inside, and the cochlea vibrate and move thousands of tiny hairs inside the ear. When these hairs move an electrical response occurs. This electrical response goes to the hearing nerve and then it is send to the brain.

Sound is energy that's released in the form of vibrations.Longitudinal wave is a wave that travels in a single direction.The ear is shaped similar to a funnel and that allows it to collect the different sound waves that can reach it.Vibrations are created by a longitudinal wave that' sent out, but it does not guarantee that anyone would be able to hear sound.

The interesting question is how waves can become meaningful sounds. First off we must know that sound is a wave. It is impossible for sound to be a particle or atom because if it was a particle the two different sounds would eventually collide and if sound was an atom one sound would deflect another and neither one of these situations ever happens. A characteristic of sound is that different sounds pass through one another, for example, a sound and its echo. Therefore, it is safe to conclude that sound is a form of wave. Sound is molecules vibrating back and forth creating what we call a longitudinal wave. However, very few times do we consider sound as flow of power yet that is exactly what it is. It is a power that flows through the air steadily. The speed at which it travels depends on the temperature and the

The sound waves are produced by a random oscillating crystal, and are inaudible to humans. A instrument called a

Transverse and Longitudinal waves are different due to the fact that Longitudinal waves are waves that vibrate in a parallel direction in a back and forth motion compared to that of the motion. However, transverse waves are when the waves moves at a perpendicular direction of the motion. They are similar because they both make waves when their is motion or energy involved in their movement.

The physiology of hearing starts with a vibration that occurs in the air which sends an acoustic signal to the ear drum. The signal is transduced into a mechanical signal that transmits through the inner ear and the cochlear nerve. Finally, the signal is

The middle ear has three ossicles (tiny bones) the hammer, the anvil, and the stirrup that connect the middle ear to the inner ear. When sound enters your middle ear, it causes the ossicles to vibrate. These vibrations then move into the cochlea, which is filled with fluid. When the vibrations move the fluid that is in the cochlea, it stimulates tiny hair cells that respond to different frequencies of sound. After the tiny hair cells are stimulated, they direct the frequencies of sound into the auditory nerve, as nerve impulses. (ASHA 2013)

The snail like shape of the cochlear effectively boosts the strength of the vibrations caused by sound, especially for low pitches. When sound waves hit the ear drum, tiny bones in the ear transmit the vibrations to the fluid of the cochlea, where they travel along a tube that winds into a spiral. The tube’s properties gradually change along its length, so the waves grow and then die away, much as an ocean wave travelling towards the shore gets taller and narrower before breaking at the beach.

Also in Jason Torres`s "Sound Is All Around Us" he says that hearing is about vibrations and it is actually our brain that tells us what is happening and what the sound is. He also said to hear sound you need something on one side to receive the sound and another side to send it to your brain. So when the vibrations hit an animal

It is within this framework that I consider important to study the way in which sound is

What is a sound wave? A sound wave is produced by a mechanical vibration, such as a tuning fork. The vibrating object causes the surrounding medium, such as air, to vibrate as well.The wave travels through the medium to a detector, like your ear, and it is heard.As with any type of wave, a sound wave is also described by it's wavelength, amplitude, period, and frequency.

The ears are one of the most complex and interesting systems thats human body has and the sounds we hear are actually in many different parts deflected, absorbed, and also filtered by our different body parts. It's then collected by our pinnae (the external part of or ears), whose dimensions further affect the sound on its way into ear. There, vibrations are translated into signals, which are interpreted by your brain. In the 1930s, two scientists at Bell Labs, Harvey Fletcher and Wilden A. Munson researched this process and what they discovered has changed and affected how we as humans understand the hearing process.

converts sound waves in the air, to nerve impulses which are sent to the brain,

As an aside, our friends who are focusing their studies on the exciting future of ‘Sound’, need not be disheartened since even after this innovation comes around,’ Sound’ shall continue to exist all around us, except within us, and that too, only when we would want it to be so. I am sure even they themselves would greatly benefit from this innovation.
