Nuevo estudio muestra que el ruido blanco de fondo mejora la audición

El ruido no es lo mismo que el ruido, e incluso un entorno silencioso no tiene el mismo efecto que el ruido blanco.

Con un fondo de ruido blanco continuo, escuchar sonidos puros se vuelve aún más preciso, como lo han demostrado investigadores de la Universidad de Basilea en un estudio en Cell Reports . Sus hallazgos podrían aplicarse al desarrollo posterior de los implantes cocleares.

A pesar de la importancia de escuchar en la comunicación humana, todavía entendemos muy poco de cómo se perciben las señales acústicas y cómo se procesan para permitirnos darles sentido. Sin embargo, una cosa está clara: cuanto más precisamente podamos distinguir los patrones de sonido, mejor será nuestra audición. Pero, ¿cómo logra el cerebro distinguir entre información relevante y menos relevante, especialmente en un entorno con ruido de fondo?

Explorando el “cerebro auditivo”

Investigadores dirigidos por la profesora Dra. Tania Rinaldi Barkat del Departamento de Biomedicina de la Universidad de Basilea han investigado los fundamentos neuronales de la percepción del sonido y la discriminación del sonido en un entorno de sonido desafiante. La atención se centró en la investigación de la corteza auditiva, el “cerebro auditivo”, es decir, el área del cerebro que procesa los estímulos acústicos. Los patrones de actividad resultantes provienen de mediciones en el cerebro de un ratón.

Como es bien sabido, la distinción entre los sonidos se hace más difícil cuanto más cerca están en el espectro de frecuencia. Inicialmente, los investigadores asumieron que el ruido adicional podría dificultar aún más la tarea de escuchar.

Sin embargo, se observó lo contrario: el equipo pudo demostrar que la capacidad del cerebro para distinguir las diferencias de tono sutiles mejoró cuando se agregó ruido blanco al fondo. En comparación con un entorno tranquilo, el ruido facilita la percepción auditiva.

El ruido reduce la actividad neuronal

Los datos del grupo de investigación mostraron que el ruido blanco inhibió significativamente la actividad de las células nerviosas en la corteza auditiva. Paradójicamente, esta supresión de la excitación neuronal condujo a una percepción más precisa de los tonos puros.

“Encontramos que se produjo una menor superposición entre las poblaciones de neuronas durante dos representaciones de tono separadas. Como resultado, la reducción general de la actividad neuronal produjo una representación de tono más clara ”.

– Prof. Dra. Tania Rinaldi Barkat, Departamento de Biomedicina, Universidad de Basilea –

Para confirmar que la corteza auditiva y no otra área del cerebro fue responsable del cambio en la percepción del sonido, los investigadores utilizaron la técnica optogenética controlada por luz. Sus hallazgos posiblemente podrían usarse para mejorar la percepción auditiva en situaciones donde los sonidos son difíciles de distinguir.

Según Barkat, es concebible que los implantes cocleares puedan ser estimulados con un efecto similar al ruido blanco para mejorar la resolución de frecuencia y, por lo tanto, el resultado auditivo de sus usuarios.
