New Infographic on Underwater Sound Terminology



In underwater acoustics, 'source level' and 'sound pressure level' are expressed in decibels (dB), but represent different physical quantities whose values are not comparable. Our new infographic shines a light on these sometimes confused terms using light as a helpful analogy. For more details on this subject, see Ainslie, Halvorsen and Robinson (2022), A Terminology Standard for Underwater Acoustics and the Benefits of International Standardization.
