Mechanical "Voice"
Most people discount the abilities of their sensory organs. Our bodies are very finely tuned machines with incredible capabilities including the ability to see in bright or low light, hear a whisper across a room, feel the lightest touch on our skin. Without these abilities, humans would have been killed off many millennia ago by superior predators.
Here's how our natural abilities play into experiencing music: People frequently tell me they can't hear the difference between speakers but they can tell the difference between their family member's or friend's voices quite easily. How is this possible?
Speakers are a mechanical "voice" that is designed to reproduce recorded sound. Subtle differences in speaker design and materials affect the "voice" of a speaker, similarly to how a very tall or large person typically has a deeper voice compared to a small child. The size of the person and relative length of the vocal cords are part of what dictates how deep or high their voice is. Likewise with speakers, larger speaker cabinets and drivers (woofers) are capable of playing deeper tones. Specialized smaller drivers (tweeters) are capable of playing higher pitched sounds. The reality is that we all are quite capable of experiencing the world around us through our senses with very minute changes in volume level, pitch, brightness, contrast, temperature, etc.
