What is Directional Acoustics Technology?
Learn about FreSound Directional Acoustics Technology
FreSound Inspiration Open Earbuds Design
The sound outlet positioned toward the front sits nearer to your ear canal, eliminating audio spillage (similar levels to semi-open earbuds) to maintain your privacy and avoid bothering people around you. The Directional Acoustics Technology is specifically engineered to minimize sound leakage, creating a private sound zone for the user. This allows individuals to listen freely without disturbing others.
Reduce Sounds Leakage with high-end Algorithm
Reverse Sound Field System
Our Purpose: To solve sound leakage.
How it Works: This is an advanced "directional sound" technology. A typical speaker driver emits sound waves in all directions (causing leakage). The Reverse Sound Field System uses the algorithm to precisely control the driver to generate two sets of sound waves:
1. Primary Sound Waves: Directed into the user's ear canal.
2. Reverse Sound Waves: Designed to have the same frequency but opposite phase as the leaked sound waves.
Result: These two sets of waves interact and cancel each other out through destructive interference, dramatically reducing sound leakage and protecting user privacy.
High-Sensitivity Driver and Algorithmic Compensation
Our Purpose: To solve sound quality issues, especially weak bass.
How it Works: Bass frequencies easily dissipate in an open-ear design. FreSound has a "Dual-magnet High-sensitivity Driver" for better physical performance.
Result: it applies dynamic EQ compensation to intelligently boost and optimize the bass frequencies that are most prone to loss, while ensuring mids and highs remain clear.
It also includes a limiter protection algorithm to prevent the diaphragm from over-excursion at high volumes, thus avoiding distortion (clipping) and ensuring clean sound even at louder levels.
Adaptive Ear Volume Model
Our Purpose: To provide a consistent listening experience regardless of individual ear shape.
How it Works: Everyone's ear anatomy (pinna shape and size) is unique, which affects how sound, particularly high frequencies, travels into the ear canal.
The Liso Algorithm contains a volume model trained on vast datasets of human ear profiles.
Result: FreSound open-ear earphones intelligently detect the user’s wearing condition and automatically adjust EQ and volume, ensuring a consistent and optimized listening experience for different users, or the same user with a slightly different fit.
