We have a staff member who talks too quietly and doesn't hear as well a 33-year-old guy should. Therefore, many conversations result in "What?" coming from both sides. Very frustrating, especially when an attempt at dialogue is taking place in a loud vehicle like the 2007 Pontiac G5. We're not suggesting the need to yell in order to be heard, but the G5's road noise, tire noise, and wind noise emanating from the door seals don't exactly add up to a serene environment. Rear seat passengers are treated to what seems like a dearth of sound insulation, making it a bit difficult to maintain easy conversation with riders up front.
