Bit Rates

How would you describe the differences between the bit rates? Why do each of them sound different from each other?

    The differences that I noticed between the bit rates were about the quality; the lower bit rates had much more distortion and sounded more muffled than the higher bit rates. The difference is especially clear at 48kbps CBR as the higher bit rates had more subtle differences. Each of them sound different from each other as bit rate dictates how much data is uploaded per second. Having a higher one allows for more information to transfer and thus a smoother experience, the opposite when it comes to lower bit rates. You can think of it like water passing through a hole; the bigger the hole(bit rate), the easier it is for water(data) to pass through. When the hole is smaller, it's much harder for the water to come out.
