PRACTICAL CONSIDERATIONS FOR MODELLING NOISE LEVELS FROM HVAC SYSTEMS
This paper outlines the fundamental principles for modelling heating, cooling, and other ventilation/pipe systems using available software tools, highlighting key diFerences across various acoustic propagation models (ISO 9613-2:2024, CNOSSOS-EU, HARMONOISE). The primary challenge is obtaining accurate input acoustic data for diFerent types of heating and cooling devices. In some cases, weighted sound power levels are provided, while in others, A-weighted sound pressure levels at 1 meter are given for devices operating at maximum capacity, often without a measured noise spectrum, which typically varies with fan speed. Several practical modelling examples are discussed, focusing on heating and cooling devices located near residential areas, incorporating relevant airborne and structural sound propagation eFects and final assessments. Additionally, noise reduction measures, for both noise and pressure drop, are presented to ensure compliance with Croatia's rigorous regulations, which generally mandate that residual noise levels must not exceed an increase of +1 dBA.

POREDBENA ISKUSTVA U REGULACIJI TEHNOLOGIJE POLUSAMOVOZEĆIH SUSTAVA U MOTORNIM VOZILIMA
Valja izložiti poredbeni modeli regulacije korištenja naprednih sustava za ispomoć u vožnji motornih vozila te sustava za automatiziranu vožnju motornih vozila. Naglasak je pri tome na američkim i europskim iskustvima u vezi uvođenja i primjene tehnologije na trećoj i četvrtoj razini autonomije (SAE klasifikacija).
