The Importance Of Sound Reflection

In the first chart, you have the distinction between soft sounds (from water drops and leaves), to medium and moderate noises (baby cries, a dog barking, and the sound of a piano), to very heavy noises (like music during a concert or a plane). Each of these noises are represented in terms of their pitch (measured in frequency), and in terms of loudness (measured in decibels). The second audiogram also follows this logic, but with less details, where your level of noise intolerance is measured vertically and horizontally. With both audiograms, the further down (vertically) you go into the graph, the least noise tolerant you become. As a first exercise we would like to give you a small frequency exercise, so that you can define how severe your hearing loss (whether you suffer from tinnitus or any other hearing loss condition). Before you complete this exercise, you should note that tones go from 8Hz all the way up to 22,000 Hz (where people over 25 are not able to hear above 15KHZ). Also, the commonly hearing range for humans is 20 Hz to 20KHZ. Below we have listed a series of frequencies (ranging from 0KHZ to 22KHZ). The aim of the exercise is to listen to each tone and note when your hearings cuts out. Start the exercise by turning the volume down on your headphones or speakers and then gradually turn it to a safe level (not too high). Overall, if you need to increase the volume as the frequency increases, then you have a serious hearing problem. Take a listen:
