Article Review: Sound Is Everywhere By Jason Wells

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

In the podcast, Sound as Touch, Radiolab conducted a study in which parents and infants were recorded to find a pattern of common tunes in the interaction, crossing all cultural barriers. When parents of different languages expressed happiness to their infants, there was rise and fall in the melody. Sound is like touch and even scientifically this makes sense. Jonah in the podcast explains that waves vibrate and travel into the listener’s ears and more specifically moving the ear bones. This way, hairs stimulate electricity and ingrains into our brain, which results in sounds.

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 something quite special, impactful, and adds layers of elements and complexity to a film. As with the progression of the movie making medium, sound has grown and changed drastically over the decades. However, sound cues in the form of effects, dialogue, and everything in between, shapes our perceptions of a scene and movie.

if you scream at the top of your lungs in a empty room and then repeat the screaming in the same room filled with furniture, you will notice that the sounds are different.That's because the waves are bouncing around the room in different patterns and are changing the way your brain is translating them.

The ear is an extraordinary human organ that many people take for granted until it doesn’t function. It is the only device that allows the human to hear sounds in their environment. The ear is made up of many parts that distinguish various sounds through different means. The ear anatomy and physiology along with how sound waves are transmitted into meaningful sounds will help one understand how hearing loss occurs.

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

5. Sound is the movement of air molecules brought about by a source of vibration. Skin senses – touch, pressure, temperature, and a pain – play a critical role in survival, making us aware of potential danger to our bodies. Thus, sound and skin senses allowed passengers to detect the aircraft’s motion. For example, ears start to feel weird and heavy pressure on your body.

People say naturally that the only way there's a sound is if you can hear it. Now, based on the two passages, 'Hearing Sound does not Require Ears' by Tabitha Callaway, and 'Sound is All around Us' by Jason Torres. Which state that sound there without us being able to hear it. As well as you not even needing ears to hear in the first place.

Sound is quite simple. It is nothing but a simple mechanical, longitudinal wave. When there is only one wave, everything is simple and easy. However, when there are two or more waves, they interfere. This mostly happens in one of two ways.

A hearing protection device (HPD) is often used as a protective measure in a workplace environment when the sound levels of that environment cannot be decreased and such levels pose a threat to the hearing of workers. An HPD is a safety device worn by individual’s to protect his or her hearing from the harmful effects of sound (Berger, 2003). A variety of occupational environments are known to produce high levels of noise, including factories and military operations. Individuals employed in these professions may be required to wear HPDs to reduce the risk of noise-induced hearing loss. However, certain situations in these work environments require the listener to also be able to hear low-level sounds for safety reasons.

Sound is an important input affecting the nervous system. The brain reacts to sound input because information signals are able to travel from the outside environment, across action potentials and through the neural

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

According to the teachings of the Sufi Order of Naqshbandi - Haqqani School of Thought, Sound and Silence are not two opposite concepts, as usually thought of. Both of them refer to Sound per se but their sources are different. The Sound, that is familiar to us, the audible Sound, is called as the Sound of the Known. On the other hand, Silence, the non-audible sound, represents the sound of the Unknown. (This reminds us of the Ahat Nada and Anahat Nada of Nada Yoga!). The Sound of the Unknown is referred to as “HU”. “Hu” is both a Sound and a Holy Name of God. The sound "Hu" is considered as the most basic vibration in the universe. It is the subtlest sound, or the smallest vibration, that is produced whenever an object moves in the universe. Since nothing in creation is in perfect state of rest (electrons are constantly moving around the nucleus), it may be safe to say that there is no place in this universe where the sound "Hu" is not produced.

Sound waves with low amplitude can only be heard so far away. With that said, the riddle’s answer if false. Just because we can not hear sound waves does not mean that a falling tree is mute of sound. Through the use of physics, one can understand that energy process of a falling tree. The conservation of energy tells us that energy cannot be destroyed nor created; therefore, energy transfers into friction, heat, velocity of the tree, and sound. To conclude, our auditory process is amazing. Transforming sound vibrations into auditory input is absolutely mind boggling. To be technical, no, a tree falling does not create audible sound when we are out of range, but to say that it doesn’t create any sound is a false
