Thunder is around 120dB but that only lasts for a short amount of time. A rocket launch will produce continuous high-intensity noise, which is far more damaging

Thunder is around 120dB but that only lasts for a short amount of time. A rocket launch will produce continuous high-intensity noise, which is far more damaging. Animals also have ways to prepare for a storm, such as retreating to a nest or other safe space as the storm comes. A rocket launch usually occurs during good weather and has no clear advanced warning, so there's no chance for mitigation. So I don't think the comparison to thunder is apt.
