Do you suffer from the “Cocktail party problem”? Is it hard to keep up with conversations amid the hubbub of ambient chatter? Reasearch suggests that in the UK alone 89% of men and 87%% of women over 55 have difficulties in noisy pubs, cafes and restaurants. A small Cambridge based audio software company claims to have the solution – but says efforts to market its Orsana“assistive listening technology” by teaming up with a big hearing aid firm have met with resistance. So AudioTelligence, which claims to have experienced a “flood” of enquiries from sufferers and audiologists, has launched a crowdfunding campaign in a bid to raise £400,000. That would cover the cost of producing an initial 1000 of the small table top devices and their accompanying wireless earbuds.
