Am steadily working my way through the red/blue warp. It is now officially more than half woven. :) This is a shawl woven with 2/10 black Tencel in twill blocks. The ribbon you see pinned to the cloth is one of several I have in various lengths. Rather than use a tape measure, I bought some hemming tape in different colours, cut them to various standard lengths, and pin them to whatever I'm weaving to measure the length I want. For shorter lengths, I'll program the actual number of picks but for longer lengths, like shawls or scarves, it's just as easy to measure with a cloth tape.
Some looms, like the Leclerc Fanny (and almost every Louet loom I've woven on) are very quiet. With the Fanny all you really hear is the slight clatter of the metal heddles as the shed is changed, and the low whump of the beater as it strikes the fell. Not even that if the weft is being placed, rather than beaten.
Other looms, like my AVL, are extremely noisy - unless you weave v-e-r-y s-l-o-w-ly. Since I'm trying to earn money by weaving, I don't have the luxury of weaving slowly/quietly.
When I got my AVL in 1984, I realized that it was much noisier than any loom I'd woven on before, partly due to the sharp clatter of the plastic pickers on the fly shuttle, partly due to the larger sized everything - more shafts, bigger beater and so on.
At the time, Doug was working for an industrial supply house, with a particular interest in safety equipment. He brought home a set of ear muffs, specifically for high impact hearing protection.
Eventually I got headphones so I could listen to books on tape or music, but always rated for high impact hearing protection.
During a recent discussion on a chat group I belong to about wearing hearing protection, one weaver commented that after weaving on her AVL for 20 years - without ever thinking about hearing protection or wearing it - she now has 50% hearing loss.
While we all have to make choices, and ultimately it really does depend on how much you weave, if you have a large AVL at least thinking about hearing protection would be a good idea. Especially if you are a young weaver with many years of weaving ahead of you.
