A non expensive sound insulation box used for aero-acoustic experiments at moderate Reynolds numbers (Re<2.10^4) and low Mach numbers (M<0.2) relevant to the study of speech production is presented. Its performance is evaluated with particular attention to unwanted noise sources inherent to the flow facility. Objective acoustic parameters of the insulation box are assessed.
