# Sound Pressure Level Formula

## Sound Pressure Level Formula

It is the pressure applied by the sound waves that is called sound pressure. Sound pressure level refers to the ratio between the actual sound pressure and the reference level, which is the lowest intensity sound that most people can hear. Basically, the sound pressure level determines how much pressure is applied to the sound.  A logarithmic measure of the difference between the rms value of the sound pressure and the reference value is provided.

### Sound Pressure Level

It is recommended that students familiarise themselves with the Sound Pressure Level Formula and its solutions in order to prepare well for the in-school examinations and other competitive examinations. To be prepared for any complicated questions on the examination, extra questions from the chapter should also be practised. Apart from practising the Sound Pressure Level Formula and its solutions, Extramarks recommends students practice a number of important questions. Moreover, these solutions clarify students’ doubts by explaining their logic in detail. Therefore, Extramarks provides students with the Sound Pressure Level Formula and its solutions in order to help them resolve all their queries. Experts with in-depth knowledge of the subject compile textbooks. Textbooks are the best resource for building students’ basic concepts. These textbooks, however, do not provide answers to their questions. Finding authentic answers to these questions can be challenging for students.
