A curse of cheap apartment housing is thin walls
that fail
to attenuate, let alone block, sound.
Good sound absorbance typically requires adding
mass,
which is difficult and expensive (e.g. bricks,
additional
layers of sheetrock on sound isolating standoff
blocks,
etc.).
Fast and
cheap sound absorbance could (in theory)
be
done like so:
A sheet of water absorbing polymer
the
size of the wall, with waterproof plastic sheet on
both
sides, adhesive on one side, and a hose port at one
corner.
Receive by mail-order, unroll it, stick it to the wall,
and
connect a garden hose from the nearest faucet to fill
it
with water.
Result: a ~6 inch thick layer of waterlogged plastic
material stuck to the wall and covering the entire
surface of the wall, weighing perhaps a ton, and
attenuating sound perhaps by a lot, since the sound
waves
dissipate in the mass of heavy damp plastic.
Not recommended for ceilings, floors, vent openings,
doors, or lightly built walls. Not to be installed
without
stamped architectural drawings approved by the
planning
office.

Poor dog. The rest of the destruction is cool though. [+] |

Water conducts sound very well, so are you sure this would work as described? |

I would hope the density changes around particles
of plastic would rapidly scatter and dissipate the
sound waves, but until someone actually builds this
(however short-lived that may be) I have no idea. |

Water conducts sound well, but I would think a
gelatinous distortable bag of it wouldn't do so well.
The physics here seem interesting. |

A thin-film reflection material for sound waves. The
plastic could be a 1/2-wavelength delay plate.
Maybe. |

Water capacitance as boundary walls? Usually water in walls is actively avoided and different materials and tanking are used if done. Plastic might condense/trap moisture. Don't want free mushrooms growing from the skirting boards. |

No, no, they're all good. It is just the farm maintenance that's overly costly. |

Bit of O2, bit of air cleaning, a patch of living space and the feel good buzz. A lot of tiny green profits. |

Darn, I was just about to inquire about the ceiling
version. Shucks. Darn. |

Got up lights/LEDS with growing frequencies? Also the herb plant's penetrating roots would have to be sealed by the ceiling drape unless it was in the bathroom. |

I once went to a cafe where one wall had a holey tube running along the top, and a trough at the bottom, so that water flowed continuously down the wall. There were lots of ferns and mosses growing on the wall. |

Hot climate? Did the cafe have a better relaxed vibe? |
