Hearing clarity—the ability to tell apart (discriminate between) similar-sounding words such as “fun” and “sun.” People with normal hearing generally have 100% discrimination. If your discrimination scores drop below 40% to 50%, you won’t understand much of what you hear, no matter how loud it is. Speech then sounds more like gibberish or a foreign language. Discrimination is always expressed as a percentage. Now called Word Recognition (WR) testing.
