Description
This soundtrack captures the noise from a 120 m long roll-on/roll-off cargo ship built in 2000 (Nohlan Ava), deemed representative of the shipping traffic in the St-Pierre-et-Miquelon harbour (France), recorded using an Aural-M2 (Multi-Electronique Inc., Rimouski, QC, Canada) underwater acoustic recorder (sampling frequency of 32 kHz, 16 bits resolution) equipped with a HTI-96-MIN hydrophone (High Tech Inc., Long Beach, MS, USA) with a sensitivity of −165 dB re V/μPa and set with a gain of 22 dB. The sound sequence was processed with Audacity® software to create an 80 min soundtrack composed of the sound of the cargo ship arrival (11 min), a 39 min break (simulating handling in harbour), its departure (8.5 min), and a new break of 21.5 min. This soundtrack was repeated in loop throughout the experiments.
