8인치 서브우퍼로 저주파를 틀면 아래층 침대에 누워 있는 사람이 불쾌한 진동을 느낄 가능성...

Considering vibrations and sound

The user is asking whether playing low-frequency sounds on an 8-inch subwoofer could create unpleasant vibrations in the bed of someone on the lower floor. I’m considering factors like the frequency, sound intensity, and building construction. There's definitely a possibility, but it depends on multiple factors: the volume, the building's structural isolation, and the resonance frequencies of the walls and floors. Ultimately, a strong enough subwoofer might cause vibrations, but the specifics will vary depending on the environment. I'll answer more fully in Korean.

Exploring vibration impact

Low-frequency sounds, like those from subwoofers (20-200 Hz range), can transmit through building structures and cause vibrations. An 8-inch subwoofer might produce less physical vibration than larger ones, but if it's played at high volumes, there's still a chance vibrations could be felt on the floor below. While it might not be as powerful at moderate levels, intense bass frequencies can amplify the effect. Using isolation pads can help reduce vibrations. I'll answer in Korean and cover these factors.
