For the first time on iPhonennAn effective hearing test that measures your threshold of hearing for sounds of different frequencies.nFind out just how far your ears can hear ranging frequencies.nMost of the people should be able to hear up to around 15kHz. From around 17kHz upwards, we get into a range that only the under 20's can hear.nnGeneral:nnThe human auditory system is sensitive to a wide range of sounds, both in terms of frequency pitch and intensity loudness.The lowest sound in pitch we can typically hear is about 20 Hz, and the highest sound 20KHz. However, we are not all equally sensitive with all differing frequencies.nnFeatures:nn With this version, you will test your frequency threshold, using static volume tones.n Using the iPhone headphones, you will be asked to adjust the iPhone volume, for clear and effective playback tones. n Your left and right ear will be tested alternately with every frequency, from the above frequency ranges.n After the test has been completed, you will get a report of your hearing frequency response.n History module lets you save your testsnnnFor Version 3.0nSome users reported a problem after updating from version 2.0.nUninstall and reinstall free charge has solved this issue.nnnnnnNew features to be released on the next version free update nn A new test to find out also your intensity threshold measured by dB.n Generate a dBHz graph according to your test result.
