Сейчас Хэмптону 67 лет, он акустический эколог — изучает звук в жилых помещениях. А также он основал в Калифорнии некоммерческую организацию Quiet Parks International

So vivid was Hempton’s awakening that he immediately dropped out of his studies, abandoning a degree in plant pathology, and changed the course of his life. Now 67, he is a renowned acoustic ecologist (someone who studies sound in living environments) and co-founder of Quiet Parks International (QPI), a California-based non-profit that identifies and preserves natural soundscapes by testing sound levels in rural and urban spaces and encouraging visitors to recognise the importance of quiet.
