What are SereneSynth focus protocols?

SereneSynth protocols are structured sound sessions built from defined acoustic conditions, research findings, and practical listening routines. They offer automated interval sequencing (such as 25-minute focus and 5-minute break blocks) with calibrated sound conditions including quiet, white noise, pink noise, brown noise, and binaural conditions.

How does brown noise support concentration?

Brown noise provides a deep acoustic spectrum with a -6 dB per octave power falloff (1/f²), attenuating sudden environmental acoustic distractions and creating a steady, low-distraction auditory background.

What acoustic conditions are investigated in the ADHD focus protocol?

The ADHD focus protocol prioritizes research-informed conditions: White Noise (primary evidence-supported condition), Pink Noise, 15-Hz Binaural (400 Hz left / 415 Hz right / 15 Hz beat / 407.5 Hz carrier — preliminary ADHD-specific human evidence for subjective studying performance), Quiet (reference), 40-Hz Binaural (experimental general-attention condition; not ADHD-specific), and Brown Noise (exploratory).

What acoustic conditions are included in the Student focus protocol?

The Student focus protocol focuses on core conditions: Quiet (primary reference), White Noise (comparison condition), and Pink Noise (comparison condition), with clearly labeled experimental conditions including 40-Hz Binaural (320 Hz left / 360 Hz right / 40 Hz beat / 340 Hz carrier), 15-Hz Binaural, and Brown Noise.

Do binaural beats require stereo headphones?

Yes. Binaural beats require stereo headphones because isolated frequencies must be delivered to each ear separately for the brainstem's superior olivary complex to compute the perceptual interaural difference frequency.

Academic & Study Framework

Student Focus Protocol (90 Minutes)

A structured sound session for studying, reading, writing, memorization, exam preparation, and sustained academic work.

Structured Study Format: 90 Minutes

Sequence: 25 min Study → 5 min Rest → 25 min Study → 5 min Rest → 25 min Study (Total: 90 minutes). Configurable to 15/5 and 30/5 intervals.

Core Study Conditions

1. Quiet — Primary Reference

Primary reference condition for quiet academic work, reading, and problem solving.

2. White Noise — Comparison Condition

Comparison condition; evidence primarily comes from ADHD/elevated-attention populations.

3. Pink Noise — Comparison Condition

Comparison condition; direct evidence for general/student populations is limited.

Experimental Conditions

40-Hz Binaural Beat — Experimental Human Attention Condition

40-Hz beat centered on a 340-Hz carrier, implemented as 320 Hz left / 360 Hz right stereo.

                  Left: 320.0 Hz | Right: 360.0 Hz | Beat: 40.0 Hz | Carrier: 340.0 Hz (Stereo Headphones Required)
                

15-Hz Binaural Beat — Experimental Condition

Experimental condition; not presented as a student-specific frequency.

Brown Noise — Exploratory Condition

Exploratory condition with -6 dB/octave power spectral slope.
