Acoustics Essays

Good acoustics within learning environments are very important as they can prevent avoidable distractions from occurring and will positively impact the pupils learning potential. Low ambient noise levels are even more essential with the requirements of the Special Educational Needs and Disability Act 2001. Acoustic standards of the new schools are to be achieved under the Building Regulations and Building Bulletin 93- Acoustic Design of Schools. The acoustics of schools is traditionally very poor

accent, and ambient miking are the four distinct methods of microphone placement. Distant miking is desired when needed to pick up a large ensemble like a symphonic orchestra. The room’s acoustics can also be preserved with this technique. Close miking on the other hand, captures the sound without the acoustics of the room. The mic is placed anywhere from one inch to three feet away from the source, so very little of the sound escapes the reach of the mic. Accent miking can be used to capture an

Stimuli For the stimuli, the same female native British English speaker used for Delle Luche et al. (2016) recorded 40 tokens of each word, “mummy” and “bummy”, in isolation and in child-directed speech, which were then narrowed down to 8 sound files. The tokens were manipulated for the ones that sounded the same with similar word patterns. All the files lasted approximately 24 seconds, and the tokens were normalised for amplitude with Praat (Weenink, 2010). Both “mummy” and “bummy” tokens were chosen

In order for one to understand the Manufacturers Specs in music production, you must first understand the element in which you 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

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

Soundation Task Song Name: Rust | Kick It Genre: Semi-electro/acoustic The soundation assessment proved to be a great chance for me to investigate different genres and areas of music creation. Not only did this piece enable me to independently choose different sounds and beats to suit my own wishes and personal preferences when it comes to music, but it opened my eyes to the world of music and electronic music creation. I personally am a fan of EDM, Dubstep and Electronic music and even though

The article focuses on the sonar of Atlantic bottlenose dolphins including its features and characteristics that make them unique to their lives. Dolphins have the widest frequency range of any animal since they are able to hear between 100 Hz and 150 kHz. The peak of the broadband clicks they make are between 120 kHz and 130 kHz and their signals can last from 40 to 70 μs. The source levels peak at 210 and 227 dB. Three experiments were made exploring the characteristics of the dolphin’s echolocating

Bats and toothed whales are model organisms for the investigation of sensory processing. These two animal groups evolved echolocation, an active sense relying on the integration of auditory, vocal and motor systems. In order to forage in darkness, these animals emit intense high frequency sounds and use information from the corresponding echoes to locate, discriminate and track prey, often at great distances, (Kloepper et al., 2014,). Sound propagating through open space is attenuated by 6 dB for

Speech Sounds, a fictional story where an entire society has gotten a plague and now none of them can speak with words, so they have to learn to use body language to communicate. This reading provides multiple themes relating to topics such as the hardships of being independent, violence, and peace. The main character of this short story is Rye, who we learns husband and children have passed, and she is on the verge of suicide because she has no one to live for until she meets Obsidian. They meet

Do you get bothered by simple sounds such as chewing, slurping, or excessive pen clicking? Chances are you might have misophonia. Some scientists believe that misophonia is quite common, happening in about 20% of the population. (Dryden-Edwards) Today, I am going to inform you about the hatred of sound, more formally known as misophonia. I chose to inform you about misophonia because you may know someone or even be someone who has this condition. To prepare, I have researched on the internet about

microphone theory and as well as technical specifications of microphones, mixing desks, sample rates, bit depth, and speakers/monitors. Equipment list Specifications Microphones: A microphone is a type of transducer that converts acoustic energy (voice, guitar, acoustic drums, piano) into electrical energy. In this report, I am going to talk about the different types of microphone, and what they are and how they work. These types of microphones are called condenser microphones and dynamic microphones

4. Topic: Behavioral Audiometry In Behavioral Observational Audiometry the observer decides if an infant is responding to a stimulus based on changes in sucking, eye gaze, and other potential reactions. The responses are then measured against the Auditory Behavior Index, which lists where the minimum response level is for typical hearing children for the first two years of life. Unfortunately, BOA is not appropriate for pure tone threshold testing of infants because the Auditory Behavior Index does

Auditory brainstem responses to complex sounds (cABRs) • Stimuli in the literature: • Vowels (both synthetic & natural) • CV syllables (synthetic, natural, & hybrid) • Words (ex: car, rose, chair) • Phrases (ex: chicken pot pie) • Environmental sounds • Non-speech vocal sounds (ex: a baby’s cry • Musical sounds and melodies Clinical Applications: The cABR is replicable across test sessions and reliably measured under passive conditions using a small number of electrodes. • Identify individuals

The final acoustic attribute that defines the sine-wave tone is its starting phase. Thit does not mean that this phase is not encoded by the auditory system. As phase differences between the sounds reaching each ear result in differences in perceived location of the sound source. The two sounds differ in frequency, with the sound cycling between periods of higher and lower air pressure at a lower rate, or frequency. These physical properties influence how it is displaced by sound; higher frequencies

pollution is thought of as physical pieces of garbage, harmful chemical agents, or biological pollutants. However, another form of pollution that spreads across our oceans includes noise pollution from a variety of natural and man-made sources. Natural acoustic pollution can originate from sources such as earthquakes, lightning strikes, volcanic eruptions, and noise from other organisms in the water (Weilgart 2007). Wilson et al. found that wind-driven waves contribute to ocean noise (1985) while Nystuen

Humans spend most of their daily listening time in an environment that contains multiple sound sources. One aspect that allows normal-hearing listeners to determine the direction of sounds and to supress background noise is the comparison of acoustic information received from the two ears (i.e. binaural hearing). Binaural hearing provides the most important cues in the form of differences in the arrival time of sounds at the two ears (interaural time differences; ITDs) and differences in the level

The Physics behind Sonography Technology Megan Rabideau November 25, 2017 Sonography is a type of imaging that uses high frequency Ultrasound Waves to produce images of the body. The Ultrasound Technology can use different frequencies depending on what is needed to record. The higher the frequency, the smaller the length of the wave will be. Higher frequency sound waves are used to produce images of the body that are closer to the outside of the body. Lower frequency sound waves are used for structures

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

(Shriberg et al., 2003) found only a 55% agreement between clinicians on 35 speech sounds in the differentiation between CAS and non-CAS groups. Furthermore, many children with CAS have co-occuring disorders and different compensatory behaviors (Strand, 2001). Despite the conflicting studies, there is a consensus among researchers that children with CAS will show deficits in one or more of the following areas: nonspeech motor behaviors, motor speech behaviors, metalinguistic awareness,

Introduction The study of the etiology of speech sound disorders (SSD) involves research into their relationship with genetic factors. The complexity of genetics leads researchers to take different approaches when pursuing investigations. Many studies analyze the association of speech and genetics by comparing and contrasting the speech traits of family members. Within this perspective, much research has been done on identical and fraternal twins. This method provides a qualitative understanding
