worth noting that as with any medical hearing test it doesn't cover the full frequency range of hearing (or, technically at least, music).
''The frequencies (or pitches) that have been used during your hearing test are shown on the horizontal axis (the vertical lines). These frequencies are low on the left side of the audiogram (250Hz), then gradually climb to higher frequencies on the right side (8000 Hz or 8kHz). Humans hear frequencies from 20 Hz up to 20,000 Hz, but an audiogram only shows a subset of our hearing range: it focuses on the frequencies that are the most important for a clear understanding of speech (the spoken words)''.
