pure copper,cold rolling,heat treatment,natural frequency,damping ratio

Some brass instrument players perceive differences in timbre depending on the material, but few studies have examined this relationship. In this study, pure copper was cold-rolled and heat-treated, and its natural frequency and damping ratio were measured. Changes in acoustic properties and microstructure are discussed.
