In reply to Woody:
"languidMandala, Do you pronounce ''fir'' and ''fur'' the same way?

Do you pronounce ''hertz'' and ''hurts'' the same way?"

Again nope.
Fir and fur are quite unlike each other. Now "for" is more malleable and can drift between "fir" and "fur" depending on the speaker.
In a scrambled sentence Hertz and hurts can sound a bit like each other but in careful, deliberate speech they are quite distinct.
