Any one knows contacts on guys who can provide acoustic panels in Mumbai.. Have an L shaped Living room.. think there is flutter echo/ reflections - plan tp put a few panels to absorb them. As its the living room, has to be aesthetic and minimal else WAF is a problem. Also debating between rockwool vs, foam. Understand there are health hazards plus irritation issue with rockwool.. came across ecose rockwool which is supposed to be more environmentally friendly.. Any suggestions would be helpful
