![]() Explore how logarithms transform large scales into manageable numbers, making the Decibel Scale a powerful tool in physics. Unpack the equation Beta 10 log (I/10-12), and marvel at the sensitivity of human hearing. Virtually all audio editors use dB labelling - it's "industry standard". Discover the magic of the Decibel Scale, the key to measuring sound intensity. Meters and Vertical Scale calibrations are inconsistent Prior art ![]() In doing the testing and image capture for this I have come to strongly think that this newly availble view for 3.3.0 would make a much better default view than the old long-standing Linear view (now Linear (amp)).Ī) this would make the default calibration of the Vertical Scale and the Meters consistent by default - and "consistency" has long been an Audacity design goal.ī) to me the new view just looks better somehow.Ĭ) it may make users less inclined to max out their recordings and edits (which happens far too often, as can be observed in postings on the Forum)ĭ) and perhaps (most importantly) it would make this nice new fearure "discoverable" rather than hiding it away in a hard to find mechanisms (right-click in VS and obscure prefs). Therefore, a logarithmic scale is used to express sound levels meaningfully in more flexible numbers rather than a linear one. ![]() The decibels logarithmic relationship allows large ranges of sound intensity to be handled in more manageable units: 10x rise in sound intensity corresponds to a 10 db. I have been working on updating the Manual for the new Linear (db) view, the linear waveform with decibel calibration (this provided by GSoC22 participant ). Medical ultrasound uses units of intensity of milliwatts per centimeter 2 (mW/cm 2 ), but the decibel is a pure number since it is the logarithmic ratio of the two intensities.
