The Effects of Head Movement and Pinnae Distortion on Sound Localisation Abstract: Human’s ability to locate sounds on their midline can be effected by the distortion of the pinnae‚ as well as the restriction of head movement. The study investigated the effects of head moment and pinnae distortion on sound localisation through the presentation of a sound stimulus along three points of the participants midline‚ in front‚ above or behind the participants head. The study was carried out under four

Auditory Processing Literature Review In the past‚ there has been difficulty in defining what is known as (central) auditory processing disorder (CAPD)‚ its definition is constantly changing with the most recent being produced by the American Speech-Language-Hearing Association (ASHA‚ 2005) stating that “(C)APD is a deficit in neural processing of auditory stimuli that is not due to higher order language‚ cognitive‚ or related factors” (ASHA‚ 2005; Wilson et al.‚ 2012) however‚ this definition

Spasmodic dysphonia is a neurological voice disorder that causes the laryngeal muscles to spasm uncontrollably during phonation (Baylor‚ Yorkston‚ & Eadie‚ 2005). Revelo‚ Underbrink‚ & Quinn state that this disorder impacts 1 in 10‚000 individuals in the United States (as cited in Mathew‚ 2014). The cause of this voice disorder is unknown at this time‚ and it affects more women than men (Baylor et al.‚ 2005). Spasmodic dysphonia causes the voice to sound unnatural and either breathy or strained‚

Sounds are waves that we hear and are caused by vibrations that travel through mediums. Depending on the medium and temperature‚ the time it takes for sound waves to travel vary. The hypothesis states that if the temperature in the air increases‚ then the speed of sound will also increase because faster-moving particles transfer energy quickly. The data collected supports the hypothesis. Therefore‚ increased air temperature affects the speed of sound because the molecules move faster‚ which causes

Lab to measure the speed of Sound Name: Nandu Pokhrel Jan 5th 2015 Abstract: The objective of this lab is to determine the speed of sound using the knowledge of waves and sounds. In this experiment you will learn how to measure the speed of sound by holding a vibrating tuning fork over an open tube of water

In Echolocation: Volume Control by Amanda Tromans‚ she explains how some animals and machines use sound to locate things instead of using vision like others. For example‚ bats‚ dolphins‚ and submarines all do this but with a few differences. This paper is more like a review so it does not show specific steps. She explains in the beginning why those exactly use echolocation; this is basically the use of echoes and soundwaves. Those echoes and soundwaves are bounced off many objects so they can get

Goals and never-ending ambitions. Sound waves travel into different organism’s ear canals but what happens when sounds are interrupted by dense walls or by a simple thin bag? Many factors can prevent multiple screams and shouts to effectively alarm and demand assistance‚ but in many cases‚ the sounds are successfully concealed as the perpetrator accomplishes their malevolent actions. Reality can cause a grown man to tremble at the sight of death and violence just like how a child begins to tremble

Strings: For a common acoustic guitar‚ there are six strings. These strings‚ either made of nylon or steel string acoustics‚ are tuned low E‚ A‚ D‚ G‚ B‚ and high E respectively. Subsequently‚ four factors determine the pitch when the strings are plucked: mass‚ tension‚ length‚ and mode of vibration. For instance‚ if you were to have a heavy string‚ it would take a longer time to vibrate‚ thus‚ giving it a lower frequency. And vice versa. However‚ frequency is not only limited to string

Tuning factor and quality factor must be considered before a decision of filter parameters(R‚ L and C). In literature‚ the study about these
