SoundCheck is a free, fun, and convenient way to find out if your hearing is within a normal range or if you have potential hearing loss. The application uses a microphone to convert sound into an electrical signal. This signal is then transferred to a device that measures the sound level in decibels. The results are displayed on a graph, and you can also use the application to check the level of your own hearing. 

The results are presented in three different ways. The first is a graph with a range of normal hearing from 60 to 140 decibels. The second is a list of three standard sound levels. The third is a list of three potential hearing levels. You can use these lists to compare your results with the results of others.
