Questions & Answers about eumhyangi jeongmal johasseo.

What does 음향 mean here? Is it the same as 소리?

음향 usually refers to sound quality, acoustics, or audio/sound system performance. In this sentence, it most likely means something like the sound or the acoustics were really good.

It is not exactly the same as 소리:

• 소리 = sound/noise/voice in a broad, everyday sense
• 음향 = audio quality, acoustics, technical or performance-related sound

So if you were talking about a concert, theater, cinema, or venue, 음향이 정말 좋았어 sounds very natural.

Why is the particle 이 used after 음향?

이 is the subject particle.

• 음향 ends in a consonant, so it takes 이
• if a noun ends in a vowel, it takes 가

So:

• 음향이 = the sound/acoustics + subject marker

In this sentence, 음향이 is the thing being described as good.

Could this sentence use 은/는 instead of 이/가?
