laminated window panes vs non-laminated

we need to replace a number of 3mm window panes that are loose. due to a neighbourhood party house, it would be very nice if we could reduce some of the low frequency, late night boom boom doof doof sounds. but, a quote from a glazier for laminated 6.38mm glass has left us gasping. eg 1100 by 1390 pane came in at a bit over $1,000. after some time googling, what we can't figure out is:the cost of the glass itself and where can we get the glass ourselves to put in, rather tha npay someone, if that is what is inflating the costs? and are we looking at the wrong sort of product for our finances? in any case, the glass has to go and i'd appreciate some suggestions.
