Coatings - Impact of coating aging on acoustic properties of spruce - DATASET

This dataset contains the experimental results supporting the research article "Effects of coating ageing on the acoustic properties of spruce wood (Picea abies)". The study investigates how nitrocellulose and polyurethane surface coatings influence the acoustic and mechanical properties of Norway spruce during a 300-day ageing period. The dataset includes measurements of gloss, hardness, impact resistance, resonance frequencies, vibration damping (tanδ), and acoustic conversion efficiency (ACE). These data provide insight into the relationships between coating ageing, surface mechanics, and acoustic performance, and may serve as a reference for further studies on resonance wood and instrument making.
