Описание (английский):

ISO 14509-3:2009 specifies the procedures for assessing sound emission of powered monohull recreational craft of length up to 24 m with a Froude number greater than 1,1. It is not applicable for personal watercraft (PWC). ISO 14509-3:2009 specifies the determination of the A-weighted sound pressure level by combining a calculation method and a measurement method.

Overview

EN ISO 14509-3:2018 (ISO 14509-3:2009 endorsed by CEN) specifies a hybrid sound assessment method for airborne noise from powered monohull recreational craft. The standard applies to craft up to 24 m in hull length with a Froude number (Fn) > 1.1 and excludes personal watercraft (PWC). It combines a calculation method for hull‑form noise with an on‑board measurement of exhaust/engine contributions to predict the A‑weighted sound pressure level (LpAmax) that would be observed at 25 m (pass‑by equivalent).

This method was developed from the SoundBoat project and provides a reproducible alternative to ISO 14509‑1 pass‑by testing that is independent of location and many weather constraints.

Key Topics

Scope & limits

Monohull recreational craft, length ≤ 24 m, Fn > 1.1; not for PWC.
Note: SoundBoat validation focused on craft with up to two chines, square transoms and hull length ≥ 11 m.

Hybrid assessment approach

Hull‑form sound is calculated from hull parameters (Annex A).
On‑board sound is measured at source (Annex B) and corrected for propagation to a 25 m reference.
Results are combined (logarithmic summation) to estimate the maximum A‑weighted sound pressure level.

Performance

Predicted LpAmax is stated to be within ±2 dB of ISO 14509‑1 pass‑by measurements (accounting for measurement uncertainties).

Reporting & test data

Test report requirements and example forms are provided (Annex C).

Normative references

Cross‑references include ISO 14509‑1, ISO 8665, ISO 8666 and IEC electroacoustic standards (IEC 60942, IEC 61672‑1).

Applications

Who uses this standard and why:

Boat manufacturers and OEMs - demonstrate conformity with noise emission requirements and support CE marking under EU Directive 2013/53/EU.

Acoustic test laboratories and marine consultants - perform reproducible noise assessments without full pass‑by setups.

Regulatory authorities and compliance engineers - evaluate conformity to recreational craft noise limits.

Naval architects and design teams - use hull‑form noise predictions during design and noise‑control optimization.

Key benefits:

Testing independent of a dedicated pass‑by site and some weather constraints.

Reproducible assessment comparable to pass‑by measurements.

Practical for early design validation and production conformity checks.
