  1. 4610. Amendment Proposal for Noise Emission Data of Motorcycles and Mopeds in CNOSSOS-EU (FA2026/132)

    A21 Transportation Noise and Vibration

    A proposal is made for revised sound source levels for motorcycles and mopeds in the CNOSSOS-EU traffic noise calculation model, which are considered too low. For motorcycles they are partly below those for cars. L-vehicles have comparatively high impact in terms of annoyance and health effects on affected residents, while comprising a small percentage of overall traffic.The proposed amendment...

  2. 4611. Impact of Noise Mitigation Solutions for L-Vehicles (FA2026/133)

    A21 Transportation Noise and Vibration

    In the EU project LENS, potential noise mitigation solutions for noise from L-vehicles were proposed. L-vehicles include motorcycles, mopeds, trikes, quads/ATVs and microcars. An impact analysis and cost-benefit analysis was made based on average Lden sound levels and on single events. Single events are the main cause of annoyance and complaints. In this paper, both methods are presented and...

    A21 Transportation Noise and Vibration

    This contribution presents results of the NEẍUS project on noise from battery electric vehicles (BEV) under acceleration in urban settings. The potential of replacing internal combustion engine (ICE) passenger cars with BEVs to reduce noise levels for residents is investigated with scenario calculations using measured traffic data and emission models generated from pass-by measurements....

  4. 4613. Beyond Decibels: Traffic Noise Severity and Acoustic Complexity in Indian Cities with Heterogeneous Traffic Conditions (FA2026/808)
    Manish Manohare (Transportation Research and Injury Prevention Centre, IIT Delhi)

    A21 Transportation Noise and Vibration

    Road traffic noise is a major contributor to environmental noise pollution in Indian urban environments, where its severity is driven by highly heterogeneous traffic conditions. These include high traffic volumes, mixed vehicular composition, variable speed and acceleration patterns, frequent lane changes, and extensive honking. Such characteristics create complex, non-stationary acoustic...

  5. 4614. Road Traffic Noise Source Inferencing in a Noisy LMIC Megacity (FA2026/935)
    Kajal Kumari (Indian Institute of Technology Delhi)
    10/09/2026, 15:00
    A21 Transportation Noise and Vibration

    Road traffic noise arises from multiple overlapping sources such as tire friction, engines, exhaust, and honking. Separating these sources is essential for assessing health impacts and developing effective mitigation strategies. Most studies report only aggregate noise levels which are insufficient for environmental impact assessment. Existing source apportionment approaches rely heavily on...
