Open in new tab Some Tentative Conclusions
- Better to have a sound wall construction than not, most times.
- Better to have absorptive panels than not.
- Reflective might be worse than nothing in some instances.
- Differences in sound absorbing panels coefficient of less than perhaps 0.3 is worth squat.
- Before putting in reflective barriers do a study to see if it makes sense
Hello,
Is this study is intended to check the optimal situation for having receivers on both two sides of the road?
if I’m interested in attenuation on just one side of the road, is it still make a big difference to have an absorptive wall compare to a reflective wall?
Can partial sound absorption come from a type of blanket hanging in trees along my acreage? Have a 100 foot tree buffer but still loud up against a 70 mile an hour highway
