Lwt(spec)=Lw+0.1*Pt+0.3 < 4.0 (Bels) where: Lw Pt dLt : A-weighted sound power level. : Value of discrete tone penalty = dLt-6.0 (dBA) : Tone-to the A-weighted sound power (Lw) with ISO 7779. Specification 29 at each octave band. 5.6.2 Discrete Tone Penalty Discrete tone penalties are added to -noise ratio taken in accordance with following formula only when determining compliance.
