Sound emission

PartAcousticsDraftv1.0.0-rc.2

A sound emission: an Emission of sound power, in decibels. It adds no fields to Emission; it only narrows it.

Fields

A module schema: it has the fields of Emission, and limits these ones further.

  • type
    One ofsound_power_levela_weighted_sound_power_level

    Sound power, as a spectrum or as an A-weighted total.

  • value
    object, fields below

    The sound power level.

    • unitRequired
      Always"dB"

      Decibels re 1 pW.
