Sound localization is the ability of a listener to identify the source or origin of a sound, in this paper we focus on the factors affecting sound localization, this study is performed to establishing whether chewing has an effect on sound localization. Chewing leads to head movements that may affect sound localization, according to previous studies undertaken head movements affect sound localization.
This paper analysis response from ten participants whose sound localization errors were recorded while and while not chewing, data collected helped test the hypothesis whether chewing affected localization. The following is an analysis of research undertaken by scholars in the past and the results of the study.
Many studies have been undertaken in the past regarding sound localization, however majority of this studies have been undertaken with immobilized heads and very few have been undertaken while respondents were chewing. A study by Wallach (1939) showed that head movements affected sound localization, in his study participants were allowed to rotate their head, tip their head and even pivoting. Results show that head movements affected sound localization by participants. However it was also evident that the sound moved with the head.
Mangles and Runge (1967) sound localization study results showed that Monaural is as good as binaural when movements were allowed, participants were a...
Hypothesis and prediction
The hypothesis that was tested is whether chewing have any effect on ability to detect the direction of sound, the null hypothesis is that chewing has no effect on sound localization and the alternative hypothesis is that chewing increased the mean error score for localization. We test this hypothesis by performing a T test that will compare the two means from the two tests, we expect that we will reject the null hypothesis that the two means are equal and accept the alternative hypothesis that states that the two means are not equal.
Null hypothesis: a = b where a is the mean error score for localization for test one and two are equal and alternative hypothesis a b or a < b meaning that the mean error score of localization for test one and two are not equal, therefore we expect to reject the null hypothesis.
In order to test our hypothesis a sample of ten individuals was randomly selected. The sample was further subdivided into two groups which included those would first chew and data collected and then data recorded with the absence of chewing. For the other group data was to be collected without chewing and then data would be collected while chewing.
The experiment was carried out using MAT LB computer software, participants sat in front of a computer and given headphones, they were then asked to locate the source of sound 180 degrees in front. The condition was that the participants would chew and then stop chewing and then they were allowed five minutes where they would continue with the second condition which is no chewing and then chew. For each of these two conditions
Chewing leads to an increase in the mean error of sound localization, this study show that chewing affects sound localization whereby the mean localization error for chewing participants was greater than the mean localization error for non chewing participants…
& Johnson, C, 2000, p.2). The DSM-III (1987) has also recognized the dependence on tobacco as a substance use disorder (Johnson, D. & Johnson, C, 2000, p.2), as tobacco addiction causes similar consequences as the addiction to any other substances cause. According to the DSM-IV, when a person suffers from three or more substance use related symptoms like tolerance, withdrawal, compulsive use of substance etc., then he can be declared as suffering from substance dependence (Johnson, D.
The use of this equipment has been used to provide students with hearing loss a better learning environment. However, it has been found that all students can and do benefit from the use of sound field amplification equipment. The sound field amplification system consists of the teacher wearing a FM microphone system that amplifies sound, making every student in the classroom has a similar experience with learning.
Use of sound and music in the film Psycho by Alfred Hitchcock
This usually happens because several sound and music editors undertake their works as smooth as possible for the audience. Besides, the perceptions that people have concerning movies is based on how cool the movie is but not on sound or music.
There is also the issue of studying the ableness of the human brain to handle and maintain thinking of the highest quality. This process is referred to as psychology. Psychology research involves trying to identify the social factors of the human brain and the biological theories and factors that underlie this process.
This paper will discuss how the elements of Storytelling, Acting, Cinematography, Editing, Sound, and Societal Impact worked together to create one of the most magnificent films to grace the silver screen. The paper will end with a criticism of the film that has won the hearts of audiences from all over the world, spanning many generations.
Besides, the perceptions that people have concerning movies is based on how cool the movie is but not on sound or music. In other words, sound and music are strongly ignored in movies (Richard 43). However, one thing
