helivõimsuse tase preferred
  • heli võimsus - helienergia, mida heliallikas kiirgab ajaühikus. Ühik: vatt (W), tähis W.
  • heli võimsustase - antud helivõimsuse ja standardse nullnivoo suhte logaritm kindlas sagedusribas või kindlal sageduskarakteristikul. Standardne nullnivoo pn 1 pW. Ühik: bell (B), tähis Lw (w lugeda alapaigutusega).
  • sound power of a source - the total sound energy radiated by the source per unit of time. The common unit is the erg per second, but the power may also be expressed in watts.
  • sound power level - ... 10Log(P/PO) in decibels where P = the sound power, PO = the reference sound power of 10 to power -12 watt (i.e. 1 picowatt), and Log = Logarithm to base 10
  • the logarithm of the ratio of a given sound power to the reference sound power. Power level in decibels is ten times the logarithm to the base ten of the ratio.

sound power level
Usage examples
  • In the case of very large machinery, instead of the sound power level, the equivalent continuous sound pressure levels at specified positions around the machinery may be indicated.

sound power level preferred
SWL
  • helivõimsuse logaritmiline mõõde tugiväärtuse suhtes
  • logarithmic measure of the power of a sound relative to a reference value
helivõimsuse tase preferred
Usage examples
  • Määrustes on sageli määratletud mõõtemeetod, mis integreerib helirõhu allikat ümbritsevale pinnale, kusjuures helivõimsuse tase määrab sellele ümbritsevale pinnale tarnitava võimsuse detsibellides ühe pikovati suhtes.
sound power level preferred
Usage examples
  • Regulations often specify a method for measurement that integrates sound pressure over a surface enclosing the source. Sound power level specifies the power delivered to that surface in decibels relative to one picowatt.
