I compared the sound of the running shower between 1) my bedroom with the door closed, 2) my bedroom with the door open and 1) bathroom.

The bedroom is larger with a more open layout, allowing more sound dispersion and less reverberation.

Even though my bedroom doesn’t have the typical soft, absorment materials like carpet or curtains, the furnite and the L-shaped layout help to reduce sound reflections and absorb sound waves. This helps in reducing echoes and creates a more dead sound environment. The sounds can be heard crispier in bedroom, because the absorbent materials help to prevent sounds from becoming muddled by reflections.

Acoustic isolation in the bedroom may be somewhat better because of the soft furnishings and potential thicker walls, which help to block out external noises.

The sounds in the bathroom can be heard very clearly from the bedroom, but the sounds from the bedroom doesnt reach the bathroom with the same quality.

Even though in the both cases the sound can be heard very well, the door being open or closed makes a great difference, indication the change in isolation.

Smaller, with a more compact shape that can cause sound to reflect more quickly, leading to a higher level or reverbation & echo.

The surfaces are consistend of hard, reflective materials like tiles, glass and mirrors, which reflects sounds rather than absorbing it, which can cause sound to bounce around the space, making it louder and more echoey. This is very noticable, since the bathroom itself is also very small and enclosed, resulting in making even low-level sound like running water or someone speaking & singing louder than they would in a bedroom.

Due to the hard, reflective surfaces, the sound is more diffuse and experience muddiness or distortion. The sound is less clearer in comparison.

The sound travels easier, resulting in the running water or vioces to be heard clearer from the other rooms.

BEDROOM: quiet & subdued & controlled & clarity

BATHROOM: loud & echoey & reflective
