System Requirements - Article Example This shows the client how accurate and secure software will be received. Software requirement document not only holds the client requirements but also the flow of the software. It tells each and every step in form of use cases that is to be performing while using software. It details the methods and plans that will be the part of testing before the submission of the project to the client. Moreover it compiles all the hardware specifications that are required for the software to run. It also holds the security plans for the software. This document helps client to estimate the software by company rules and regulation in addition of the requirements defined. Software requirement specification satisfies the client how accurate, modularized, prioritize; secure, analyzed, complete, verified and testable the software will be when developed. Not only client it helps the developer in the next phase to develop the software accordingly. How the software should be divided When to deliver which function Which function should be worked on earlier Etc. The paramount reason for system specification that later in the middle of production if team changes or any of the senior changes especially the on who interacts the client changes can get updated to the project then and there. If Software specification document would not prepared later... Engineering is the process to solve a problem. This involves steps like, analyzing the problem, thinking of different solutions, deciding which is best solution, calculation, evaluations, working to solve the problem and last but not least testing if the problem solved in a right manner or not. As science divides itself in number of different fields similarly engineering can be done in each field. The most common and known example of engineering is civil engineering. Sometimes we think that how these big bridges over the sea lay up Who are ones and how they made airplanes What made these cars run on roads Etc. these few kind of questions arose many times in mind. These all includes in civil engineering. Civil engineers are intelligent moreover bold enough to work for the convenience of people. They work day and night to plan the routes for roads, Design Bridge that allows people to cross huge rivers and seas. Civil engineering passes through with same set of steps as other engineering. That is, they analyze the problem, think what solution can be, calculate and decide which solutions fit best to solve the problem. Plan it, design it, and hire other people in their teams to help them implement the solution. Test in different ways and then allow the public to use it. Considering engineering, then civil engineering is same as software engineering. The only difference in civil engineering and software engineering is that if engineering fails, software crashes the maximum can be is, data is lost but in case of civil engineering the loss can be the human creatures. Thus, engineering should be done very carefully. That is requirements should be

Audiometry Lab Report Example | Topics and Well Written Essays - 500 words

Audiometry - Lab Report Example It also assists in assessing the nature, degree, and probable cause of the hearing impairment of s patient. The pure tone audiometry is used in determining the threshold of hearing of the patient. This is defined by the lowest hearing level at which the patient responds at least 51% of the time to auditory stimuli. These thresholds are found using procedures as recommended by the American Speech-Language-Hearing Association. Pure tone threshold testing should be handled in a sound controlled room. This will help in avoiding masking by unacceptable noise levels in the room. An audiogram is composed of three main parts namely, pure tone testing that determines ability to detect sound, and speech testing determines ability to decode sound, and tympanometry which helps in defining where the problem is. The normal hearing ability ranges between 10 - 25 dB HL while for serve cases it ranges between severe 70 - 85 dB HL. For the first patient, the left ear, frequencies between 0-2000(Hz), the hearing ability ranges between -20—50dBHL. As the rate increases past 2000 Hz, the hearing ability increases from -30 to -10 dBHL. However, when the rate hits past 4000 Hz, the hearing ability decreases to -36 dBHL. On the other hand, the right ear, the hearing ability increases gradually except when the frequency reaches 250-500 Hz where the hearing ability remains constant. However, this shows the right ear has a better listening ability. For the second patient, the hearing ability varies between different frequencies. In the left ear, the hearing ability increases between 250-2000 Hz. However, when the frequency goes past 2000 Hz, the hearing ability starts to decrease. This illustrates that when sound frequency goes beyond 2000 Hz, the hearing ability of the left ear becomes null. However, for the left ear, the hearing ability increases. The majority of thresholds are roughly 0 dB HL for a healthy ear. Points under 0 dB HL on the scale designate
