Описание (английский):

Diese Internationale Norm befaßt sich mit der praktischen Auswahl von Schalldämpfern zur Lärmminderung in gasförmigen Medien. Sie legt die akustischen und betriebstechnischen Anforderungen fest, die zwischen dem Lieferanten oder Hersteller und dem Anwender eines Schalldämpfers zu vereinbaren sind. Diese Internationale Norm beschreibt die grundlegenden Wirkprinzipien, ist jedoch keine Anleitung für die Auslegung von Schalldämpfern.

Overview - EN ISO 14163:1998 (Acoustics - Guidelines for noise control by silencers)

EN ISO 14163:1998 (ISO 14163:1998) provides systematic guidelines for the selection, specification and practical use of silencers for noise control in gaseous media. It describes principles of operation and performance characteristics of common silencer types (dissipative, reactive and blow-off silencers) and sets out the acoustical and operational requirements to be agreed between supplier and user. This document is a guideline rather than a silencer design manual and does not cover active noise-control systems in detail.

Key topics and technical requirements

Scope and purpose: Practical selection of silencers for HVAC, engine intake/exhaust, fans, compressors, turbines and pressure release lines.

Types of silencers: Definitions and operating principles for dissipative (absorptive), reactive (reflective/resonator) and blow-off silencers.

Performance metrics: Definitions and use of insertion loss, insertion sound pressure level difference, transmission loss, discontinuity attenuation, propagation loss (dB/m), outlet reflection loss, and pressure loss.

Acoustic behavior: Discussion of modes, cut-on frequency (e.g., circular duct: f ≈ 0.57·c/D; rectangular duct: f ≈ 0.5·c/H), spectral effects and modal attenuation.

Operational constraints: Pressure loss limits, regenerated (flow) noise, abrasion, corrosion, fire and explosion protection, hygienic/contamination risks, inspection and cleaning.

Specification items: Required sound levels at immission points, permissible pressure loss, physical size limits, materials and durability.

Measurement and testing: References to laboratory and in-situ measurement methods for insertion loss, flow noise and total pressure loss.

Practical applications and benefits

Use this standard to select and specify silencers that meet workplace, neighborhood or equipment noise requirements while respecting flow and safety constraints.

Apply guidance when reducing HVAC duct noise, preventing crosstalk between rooms, attenuating engine intake/exhaust noise, or controlling blow-off and pressure-release noise.

Helps balance noise attenuation against pressure loss, size, material compatibility and maintenance needs.
