you are wise for the repairing the noise problem, but must learn sound
and hearing is a guy thing. like dolby surround sound being better than
the tv speakers, audio for the home is your responsibility and so is
repairing the dishwasher. so make it up to her with a high volume
adjustable showerhead and a 75 gallon hot water tank for the family if
you can fit it into the utility room.
that will set her home comfort level up while you shop for that new
bigger energy star sony tv you really didn't need to replace just yet.
