The Blue Planet II executive producer has insisted the underwater sound effects criticised by viewers are 'representative' of nature.
Some of the ten million people watching the hit BBC nature programme each week have slammed the sounds as 'ridiculous', 'awful' and 'nonsensical'.

But James Honeyborne said the production team worked extremely hard on audio quality after facing trouble because sound travels much faster in water than in air.
Mr Honeyborne, who spent four years making the show, told Radio Times: 'We can't capture every sound under water – it's impractical if you're in a submarine.

And Bill Pound said: 'Why do we have to suffer the ubiquitous music and sound effects? No need. Nature doesn't.'
Viewers - Music - Soundtrack - Mr - Honeyborne
Other viewers said the music soundtrack was distracting, but Mr Honeyborne said the producers had carefully monitored levels by using a normal TV set.
He added: 'We sit and we actually listen to the finished film on a normal television, because it's all very well doing it in a big music theatre, but at the end of the day this is being made for a television audience....
