Several comments and comprehensive bibliographical references are also provided for each drawn page to enlarge the range of subjects or exercises that can be discussed in courses and foster further readings. the decibel value of a signal increases with if the signal is doubled (L 10 log (2) 3) If the decibel value and reference level. A decibel is one-tenth of a - named after Alexander Graham Bell, the inventor of the telephone. The signal units depends on the nature of the signal - can be.

Seven drawn pages constitute a visual support to explain the origin and history of the decibel, together with examples from acoustics and other domains on the use of logarithmic scales and classical decibel calculations. Decibel is a dimensionless value of relative ratios. This paper is an example of how educational comics can be designed and used to introduce one of the most commonly discussed topics when the basics of acoustics are taught: decibel level. While they are valuable resources for researchers, these books might appear a little daunting for a young audience or for people who are new to acoustics.

A fundamental feature of this type of logarithmic scale is that each unit of. In fact, the fields of acoustics cover an especially broad range of subjects and domains, and comprehensive acoustics textbooks are usually quite thick as a consequence. A fundamental feature of this type of logarithmic scale is that each unit of. Acoustics is generally defined as the science that deals with the production, transmission, and reception of sound and the understanding and control of its effects.
