How Technology Affects Society Today, our world is run by technology and electronics. Technology has many positive impacts and created many advancements in society. Although there have been many creations and inventions making our lives easier, it comes at a cost. This is creating the current generation as well as future generations to evolve, but not in such a positive way. There is starting to be more of a negative change in newer generations, technology is improving. Technology creates

Change in pressure For a balloon to be blown up the pressure inside the walls of the balloon must be higher than the pressure outside of the balloon. In most instances, the balloon will be filled with air. With an air-filled balloon the air pressure inside the balloon is stronger than both the air pressure of the surrounding area, and the tension force that is created by the elastic balloon covering. The balloon can be considered a closed system. This is due to the balloon does not trade matter

mechanics of a speaker is. Curious yet? I will teach you about these 2 main topics, how sound works, and how speakers work. Speakers create sound waves, but what is sound? Inside the ear, there is a thin cone-shaped membrane called the eardrum (encyclopedia britannica n.d.) When the eardrum vibrates, your brain translates it to a sound (Harris, Tom 2001). The most common vibration is rapid changes in air pressure. Sound is created when an object vibrates in the air. The air particles around the object

innovations in sound that have stretched the limitations of sound production, exhibition and understanding, but before we look at these innovations we first need to identify what sound is. Sound is created essentially by frequent changes in both the pressure and the density of air molecules within the Earths atmosphere, otherwise known as ‘Sound pressure and the fluctuations in pressure as sound waves’ . Bodies that are vibrating and traveling from one point to another create sound waves and

first to discover that sound moves in waves. Leonardo Da Vinci made this discovery around the year of 1500. Later on, Galileo Galilei discovered more about how sound moves in waves. He learned that the frequency of sound waves show how pitched the sound will be. Marin Mersenne was the first person to discover how fast sound travels from one medium to another in the year 1640. Sound is made when something starts to vibrate, it travels from one medium to another. The sound moves through a mediums

using a logic rhythmic scale that measures relative intensity. What this means is the louder an object is, the more sound pressure it makes. Sound moves at 761 mph, and no matter how loud you crank up the volume, you won’t be able to increase the sound of speed. However, cranking up the sound does compresses air pressure, which gives the impression of increased sound. This pressure is measured in decibels. 100-Watt Decibels Compared to 200-Watt

Many people do not consider everything that happens within their body when they produce sounds, as it is an everyday and seemingly simplistic occurrence. However, the production of speech is an extremely complex process that requires extensive work and compliance from various areas within the body. Speech production begins in the brain and finishes when the sounds exit the mouth and are picked up by a receiver. The processes involved in the production of speech are respiration, phonation, articulation

Aim: The aim of this project is to determine the ear's ability to allow us to perceive the pitch of sounds by detection of the wave's frequencies, the loudness of sound by detection of the wave's amplitude and the timbre of the sound by the detection of the various frequencies that make up a complex sound wave. Introduction: Understanding how humans hear is a complex subject involving the fields of physiology, psychology and acoustics. The ear consists of three basic parts - the outer ear, the

affect the transmission of sound to the cochlea. While the majority of these structures promote amplification of sound, the muscles of the middle ear actually serve to protect hearing from damage caused by loud sounds. The tensor tympani and stapedius muscle work together to activate the acoustic reflex when needed. The tensor tympani and the stapedius muscle serve to “increase resonant frequency of the middle ear to protect the inner ear from high sound pressure levels”(Pau, Punke, Zehlicke

travels through different mediums such as air or water but also through solids like in different metals. Sound wave travel through those mediums and they are created by vibration of object, which causes the air to vibrate as well. The vibrating air reaches the ear where the eardrums can start to vibrate and therefore the brain can interpret it as a sound. This process is done by the auditory system. Sound waves are put into graphs and the resulting curve is known as the “waveform” Even though the waveform

convert acoustic sounds to electrical signals and stimulate auditory nerves. The clinical treatment for the hearing loss in both children and adults is by using the artificial cochlea. This device bypasses the damaged hair cells by generating the electric current in response to acoustic sound. Current artificial cochlea consist of an implantable electrode array for the stimulation and an extracorporeal device including a microphone [1], a sound processor and a battery. Acoustic sound is detected and

will be working with. Sound So what is sound? Sound is a series of vibrations that travel through the air pressure or any other medium. We pick up the vibrations when they vibrate our eardrums. Sound is measured in Hertz (Hz) and as humans, we can hear from 20Hz – 20,000Hz(20kHz) and as our ears are picking it up, it’s moving at a speed of 1130 ft/s. Sound requires a medium to travel and the medium is the air pressure. What this means is that when the atmospheric air pressure is higher than normal

The Sound and Music Industry There are 4 main aspects of the music industry : Live performances,Record Labels,Artist Management and Music Publishing. I will be studying each one in detail and comment critically on each area. The first one I will report on is Live Performance. There are many important roles in the music industry. Many types of musicians, including backing musicians, function bands, residency bands (e.g. hotels, cruise ships) and tribute bands, perform wholly or mainly original material

The speed of sound is the distance travelled per unit time by a sound wave. The speed of sound is 331 m/s. The second concept that I used was the concept of wavelength. A wavelength is the distance between two points that are next to each other and are the same points in a wave. To find the wavelength one

voice evaluation for further assessment and recommendations (Pena-Brooks & Hedge, 2007). Resonance disorders can be assessed during the oral peripheral examination by observing movement of the velopharyngeal mechanism during phonation of the /a/ sound. In addition, the presence of hypernasality and nasal emissions should be ascertained during the examination (Pena-Brooks & Hedge, 2007). Treatment Programs or Methods One piece of advice Knutson (2015) offers to speech-language

Myths About Vinyl Annie Dillingham February 23, 2023 Vinyl is a fun and unique way to listen to music, and it never goes out of style. Rather than listening to digital music on your phone, you can listen to a vinyl record with a rich and warm sound that is unlike any other platform. Perhaps other music platforms are more convenient, but listening to a record is an immersive experience that anyone anywhere can enjoy. With this hobby, you can tangibly hold your favorite album all while admiring

Noise creates Damage Noise can be defined as a non-harmonious or discordant group of sounds, in other words an unpleasant or annoying sensation. Almost everyone knows of a particular noise that makes their stomach tight and jaw clench, for instance, nails on a chalk board or a siren. Although many think nothing of it, the reaction that the human body has to unpleasant and scattered noises is linked to stress, aggression and anger. George Prochnik, author of In Pursuit of Silence(2010), argues

Sound assignment All sounds are created by vibration. The vibrations create a sound wave in the air by pushing air particles together and spreading them apart many times. 1) Explain what frequency and pitch mean when referring to sound Frequency=The rate per second of a vibration constituting a wave, either in a material (sound waves), or in an electromagnetic field (radio waves and light) pitch= the quality of a sound governed by the rate of vibrations producing it, the degree of highness or

deafness happen? To start with, let’s briefly see how the ear works. Sound waves start by entering the outer ear; vibrations impact the ear drum after which they get transmitted immediately to the middle and inner ear. The inner ear contains a structure known as cochlear that is lined with microscopic hairs and filled with fluid. The fine hairs move with the vibrations converting the sound waves into nerve impulses. The sound we hear is a result
