Shoertly if you need it inside one class/module: I use hash but you can put there array of elements etc.

}

def do_smth1(v)
...
end

def do_smth(sound,v)
...
end

#getter
PETS.each{ |k,v| define_method(k){ do_smth1(v) } }

#setter
PETS.each{ |k,v| define_method("#{k}="){|sound| do_smth2(sound, v) }
