The work of acoustic engineers helps create a comfortable place to learn, where students hear what their teachers are saying 1. Acoustic engineers also provide guidance for builders and architects. Acoustic engineers are often hired to improve the way schools are built and make sure they are made of the best materials, to ensure communication is as clear as possible. We call this the signal-to-noise ratio, and this is where acoustical engineering comes in! Acoustic engineers can help design classrooms to reduce the amount of distracting noise coming from outside and to help manage noise created by students inside. For a classroom to work well, students need to hear more of the signal and less of the noise. Noise includes the distracting sounds the person does not want to hear. In our example, the signal is the teacher talking. We call the sound a person wants to hear the signal. Students in a classroom need to be able to hear the teacher talking without being distracted by other sounds such as their friends chatting, the sound of a passing truck or a football match being played outside. However, creating a space where communication is easy is not actually as simple as it might seem. Classrooms are spaces where we communicate with others to help increase our knowledge and understanding of the world around us. What is a classroom for? Well, it is a space where people can learn by listening to a teacher and talking with other students. One place acoustics has an especially big effect is in the classroom-you can not learn if cannot communicate! Clear Communication In the past 30 years, acoustic engineers have helped a million people across the world overcome hearing challenges using bionic implants, and they have helped hundreds of millions of people through hearing aids. Yet, imagine life without your sense of hearing! No music, no laughter, no talking, no singing? When you think of how much we rely on sound, it is surprising that so many people have never heard of acoustics! Of course, some people do not have the ability to hear. Why do people know so little about the science of sound? Perhaps it is because many of us take sound and hearing for granted. The Science Of SoundĪcoustics, the science of sound, is a science that you might not have heard much, if anything, about. We even have some experiments that you can do to measure sounds at home, at school, or in a football stadium. You will learn how sound is measured and how people called acoustics engineers help architects and designers to make sure classrooms are not too noisy-or too quiet. No ads, no hidden stuff.In this article we will study sound-specifically, how sound allows us to communicate in a classroom and how we can improve that communication.

The incorporated DSP algorithm is not signal energy based, therefore this whistle detector is much more accurate and reliable than similar applications found elsewhere on the Android Market.The application has been designed and strongly optimised in order to reduce the battery drain as much as possible.It is totally free application. The preferences can be set if you run the Whistle Phone Locator as regular Android application from the applications menu.The application uses sophisticated, but computationally optimised Digital Signal Processing (DSP) techniques to analyse captured audio signals from the environment and searches for distinct time-frequency patterns of typical human whistle. Just tap the widget and change the state from 'paused' to 'active' and vice-versa. However, the widget is designed to resume your current Media Volume when audio notification is not played.User interacts with this application via widget. In preferences user can select (approve) also the usage of maximum volume for audio notification regardless of current Media Volume settings.

Furthermore, the display of sleeping device is illuminated in order to easily locate your device in your bag for example. Tap on widget to start the whistle detector!Once your whistle is detected, the Android device will respond to your whistling with audio notification signal (one of two different audio responses can be selected in preferences). with just a simple whistle!After installation long-press on some empty space of the Home screen of your device and select Whistle Phone Locator widget. Whistle Phone Locator is Android widget (Home screen) application which helps you to locate your Android device lost, forgotten, or hidden somewhere in your room, on the desk behind the papers, in your briefcase, in the pocket of your coat etc.
