Our Adaptive Volume feature is designed to tailor the difficulty of auditory exercises to each user's hearing abilities, ensuring an effective and personalized training experience.
Adaptive Volume
- Real-Time Adjustments: The Adaptive Volume feature dynamically adjusts the volume of background noise during auditory exercises.
- Purpose: This ensures that users are consistently challenged at an appropriate level, helping to improve their ability to understand speech in noisy environments.
Hearing Scoring
- Initial Assessment: Users undergo an initial assessment to determine their baseline hearing ability and sensitivity to background noise.
- Scoring Criteria: Scores are based on the user's ability to understand speech against varying levels of background noise. This involves:
- Accuracy: How accurately the user can repeat or comprehend speech.
- Noise Intensity: The level of background noise present during the exercise.
- Response Time: How quickly the user can process and respond to speech.
Integration of Adaptive Volume and Hearing Scoring
- Starting Point: Based on the initial assessment, users begin with a customized volume level for background noise that aligns with their current hearing abilities.
- Dynamic Adjustments:
- As users perform exercises, the Adaptive Volume feature continuously adjusts the noise intensity.
- If a user is performing well, the background noise volume may increase to provide a greater challenge.
- Conversely, if a user is struggling, the background noise volume may decrease to make the exercise more manageable.
- Ongoing Assessment:
- Users are regularly scored on their performance during exercises.
- Scores are calculated based on accuracy, noise intensity, and response time.
- Progressive Difficulty:
- The system uses these scores to adapt future exercises, ensuring that users are gradually exposed to higher levels of background noise as their skills improve.
- This progressive increase in difficulty helps users build their ability to understand speech in increasingly noisy environments.
Speech in Noise - Thresholds of Understanding in Environments
- Very Quiet (1-10)
- SNR Range: +15 dB and above
- Description: Speech is significantly louder than background noise. Users can easily follow conversations without any strain.
- Real-World Scenario: Having a conversation in a quiet room where there is minimal background noise.
- Quiet (11-30)
- SNR Range: +10 to +14 dB
- Description: Comfortable listening environment with some background noise, but speech remains clearly intelligible.
- Real-World Scenario: Talking in a car with low road noise or in an office with mild ambient sound.
- Moderately Loud (31-50)
- SNR Range: +5 to +9 dB
- Description: Moderate background noise where users can understand speech with some effort; may miss nuances or lower-spoken words.
- Real-World Scenario: Conversations in a busy cafe or during a family dinner in a moderately noisy home.
- Noisy (51-70)
- SNR Range: +1 to +4 dB
- Description: Background noise is close to the level of speech; understanding requires considerable effort.
- Real-World Scenario: Talking in a noisy restaurant or at a social gathering with background music and chatter.
- Very Noisy (71-90)
- SNR Range: 0 to +4 dB
- Description: Speech and noise are at similar levels; understanding speech requires significant effort and concentration.
- Real-World Scenario: Trying to communicate in environments like busy urban streets or crowded public transit.
- Extremely Noisy (90-100)
- SNR Range: Below 0 dB
- Description: Background noise is louder than speech, making it very difficult to follow conversations without additional auditory and visual support.
- Real-World Scenario: Attempting to hold a conversation in very loud settings such as near heavy machinery, during loud events, or in entertainment venues.
Rapid Speech - Compression Ratio (CR) Categories
- Deliberate (1-10)
- CR Range: Below 0.35
- Description: Extremely slow and deliberate speech for clear comprehension.
- Real-World Scenario: Interactions requiring extremely slow and repetitive speech, possibly supplemented with visual aids or sign language.
- Leisurely (11-30)
- CR Range: 0.5 to 0.35
- Description: Much slower than normal speech to ensure clarity and comprehension.
- Real-World Scenario: Situations like therapy sessions or instructional environments where speech is slow-paced and highly controlled.
- Clear (31-50)
- CR Range: 0.7 to 0.55
- Description: Clear and somewhat slower than usual speech to facilitate understanding.
- Real-World Scenario: Settings such as customer service interactions or educational videos designed for non-native speakers.
- Casual (51-70)
- CR Range: 0.85 to 0.75
- Description: Deliberate speech to aid comprehension, typical in learning or detailed explanation contexts.
- Real-World Scenario: Casual conversations where speakers intentionally slow down, like explaining directions or teaching.
- Fluid (71-90)
- CR Range: 1.0 to 0.9
- Description: Conversations feel natural and fluid, with minimal need for repetitions.
- Real-World Scenario: Participating in everyday conversations that flow quickly or watching a news broadcast.
- Rapid (90-100)
- CR Range: 1.1 to 1.05
- Description: Involves rapid exchanges without missing details, suitable for very fast-paced and demanding settings.
- Real-World Scenario: Listening to rapid details at the end of a drug commercial or following fast sports commentary.
Key Points
- Personalized Experience: Adaptive Volume ensures each user receives a personalized training experience tailored to their hearing abilities.
- Continuous Challenge: By dynamically adjusting the noise level, users are continually challenged at an appropriate level.
- Effective Training: This approach helps users progressively improve their ability to understand speech in noisy environments, which is crucial for real-world listening situations.
Our Adaptive Volume feature, combined with our detailed Hearing Scoring system, ensures that users receive the most effective and personalized auditory training experience possible.
