Becoming a competitive swimmer means everything to Mariana, an athlete with hearing loss who has defied the odds and achieved results in the pool that once seemed unimaginable.
Born prematurely and weighing less than 1 kg, doctors painted a bleak picture of Mariana’s future. They suggested she might survive but risked going blind and deaf.
However, Mariana’s perseverance and resilience, along with the unwavering support of her family, have paved the way for her to beat the odds.
A turning point in Mariana’s life came when she upgraded to the Cochlear™ Nucleus® 8 Sound Processor. Having the latest technology has redefined her perception of the world.
“The Nucleus 8 changed my life – I can hear more clearly than ever.”
Now a World Cup athlete, Mariana sees swimming as more than just a sport. She says it defines her. It makes her feel “alive” and brings her unparalleled joy.

Mariana acknowledges that she owes her success to dedication, hard work and the unwavering support of her family. But she is also quick to highlight the impact her new sound processor and Aqua+ kit have had, helping her both in training and competition.
“Nucleus 8 radically changed my entire life, and now I can hear my coach when I am in the pool. It’s a dream come true. Aqua+ is immensely helpful during my daily swimming training,” she says.

Benefits beyond the pool
While much of Mariana’s life is spent in the pool, upgrading her sound processor has also brought significant benefits in other aspects of her life – from improved hearing in noisy situations to being able to enjoy music.
“I attended an event in my city with a musical performance, many children, and loud conversations. It was then that I realised the substantial difference in sound quality,” she says.
