Hello Sujit!

Hope you are having a nice day!

I would like to inform you that a locus of points is the set of points, and only those points, that satisfies given conditions. The locus of points at a given distance from a given point is a circle whose center is the given point and whose radius is the given distance.

And audiometry is the branch of audiology science and the measuring of the hearing acuity for vibration in sound intensity and pitch and for tonal purity, involving thresholds and differing frequencies. An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone). Hearing occurs when sound waves stimulate the nerves of the inner ear. They can also pass through the bones around and behind the ear (bone conduction).  Keep studying keep growing.

All the best for your future!

Thanks.
