NEUROSCIENCE AUDITIVE

Synthèse Binaurale, Porteuses Doubles & Entraînement Cérébral

La synthèse repose sur l'émission de deux fréquences mathématiquement distinctes dans chaque oreille via des canaux isolés. Le cortex auditif traite le différentiel pour créer une onde pulsée.

Alpha (8Hz – 14Hz)Concentration Paisible

Favorise la vivacité d'esprit calme et l'attention soutenue.

Bêta (14Hz – 30Hz)Cognition Active

Stimule la pensée analytique, la résolution de problèmes et la vigilance.

Thêta (4Hz – 8Hz)Méditation Profonde

Associée au sommeil paradoxal, à la créativité et à la relaxation profonde.

Technical FAQs & Helpful Content

FAQ Battements Binauraux

关于此项诊断工具、校准步骤及显示器技术标准所需了解的一切。

01.What are binaural beats and how do they work?

Binaural beats occur when two pure sine waves of slightly different frequencies (e.g. 200Hz and 210Hz) are played independently into each ear via headphones. The brain perceives a third rhythmic pulsing beat equal to the frequency difference (10Hz).

02.Why are stereo headphones mandatory for binaural beat listening?

Binaural beats rely on strict channel isolation (left ear receiving frequency A, right ear receiving frequency B). Monophonic sound or room speakers mix the soundwaves in open air, destroying the auditory illusion.

03.What are the 5 main brainwave frequency bands used in binaural beats?

Delta (0.5Hz–4Hz, deep sleep), Theta (4Hz–8Hz, meditation/REM), Alpha (8Hz–14Hz, relaxed focus), Beta (14Hz–30Hz, active alertness), and Gamma (30Hz–50Hz, peak concentration).

04.What is the optimal carrier frequency for generating binaural beats?

Carrier frequencies between 200Hz and 500Hz yield the strongest perceptual brainstem response in human auditory processing centers.

05.What is the difference between binaural beats and monaural beats?

Binaural beats are created inside the brain's superior olivary complex via stereo headphones. Monaural beats are created electronically before audio reaches the ears and can be heard over open speakers.

06.Can binaural beats help increase focus during studying or working?

Alpha (10Hz) and Beta (18Hz) binaural beats encourage entrainment of neural oscillations, promoting sustained attention and cognitive performance.

07.Why should I use a Web Audio binaural beats generator over MP3 audio files?

Web Audio API synthesizes mathematically pure, uncompressed 64-bit floating-point sine waves in real time, eliminating MP3 compression phase distortion and audio looping seams.

08.Are binaural beats safe to listen to every day?

Yes, binaural beats are non-invasive acoustic illusions completely safe at comfortable volume levels. Avoid listening at high volumes to protect hearing health.

09.How long should a binaural beat session last?

Most auditory entrainment studies recommend listening for 15 to 30 minutes to allow your brainwaves to synchronize with the beat frequency.

10.Can binaural beats be combined with ambient white noise or rain sounds?

Yes. Adding pink or brown noise masks ambient room distractions while maintaining pure binaural frequency entrainment.
