Brass vs aluminum
The stethoscope is carefully designed to amplify the sounds of the inner body, usually the lungs or the heart in order to detect any irregularities. Due to the functions of the stethoscope, it is clear that optimal clarity is of the utmost importance. The majority of stethoscope chest-pieces are made of either aluminum, stainless steel, or chrome plated brass, but today, we’re here to talk about brass specifically.
Well, think about it, what are the majority of orchestra instruments made of? Brass. There has to be a reason for this, but why? Brass is the product of mixing together zinc and copper, which produces the most genuine sound, rich tones, and generates an acoustically superior sound to other materials. Brass picks up low frequencies, since brass instruments sound comes from differing vibrations of the player’s lips. Centuries of using brass sections for instruments has proven to deliver the most reliable and vibrant sounds of any other medium. Orchestras are revered for their brilliant, vivid music played by their brass instruments. So, the question really shouldn’t be “why brass?” But “why not brass?”
