Can’t hear the Blue Planet II commentary? Get your ears tested | Brief letters
Blue Planet II | Charles Manson | Smoking in French films | Theresa May at church | Driverless government
As a sufferer of hyperacusis (extreme sensitivity to loud noise) I was anxious about watching Blue Planet II, following complaints about invasively loud music (Letters, 17 November). Having now enjoyed three episodes without issue, might I gently suggest that those struggling should get their hearing tested, as I suspect that, in order to hear the commentary (and not because of the music), they are turning the sound up way too high.

• Charles Manson was, according to your obituary (21 November), “responsible for the most infamous mass murder of the 20th century” yet “was never convicted of killing anyone personally”. I guess Adolf Hitler might surpass Manson by a factor of about a million in accomplishment of appalling actions. We, in the 21st century, might still need to focus on big issues and not minor events, tragic though they were in Manson’s case.
