Listening Care aims to optimize the volume balance based on a static (unchanging) volume setting on your device. However things like the volume of the content itself as the dynamic range and recording level of the music varies, as well background noise level which is likely to result in volume changes on your device can impact this. Most notably, in times of high background noise it is often desirable to increase the volume.
Listening Care on the EP-E70/YH-E700 takes a real-time, adaptive approach that uses the data for the past 5 seconds, calculating the average volume level every 0.7ms. The correction applied across a 4-band EQ is adaptive according to the average volume level. Optimization is therefore realized with significantly higher accuracy, relative to the content volume on an ongoing basis. Further, in order to obtain a more natural effect, the correction parameters are applied slowly over time. Your listening experience is customized to the music and your surroundings meaning a completely individualized sound, just for you.
Listening through headphones or earphones helps to block out the world and immerse yourself in your chosen music or audio. However blocking out the world may mean blocking important noises, such as an ambulance siren, a car horn or public transport announcements. Such important sounds might be necessary for you to avoid a potential accident or ensure you arrive to your destination on time.
Yamaha’s Ambient Sound function uses the built-in microphone to capture these external sounds, presenting them in the background while listening to your chosen audio, keeping you fully aware of your surroundings.
The size and shape of our head and ears impact the way each person interprets sound coming from headphones and earphones.
Yamaha’s Listening Optimizer utilizes an in-ear microphone to measure the seal and air leakage from different shaped ears every 20 seconds. Playback is optimized in real-time to correct the difference between the source and the actual listening condition, delivering a sound customized to the individual listener.
Active noise cancellation has a reputation for losing low frequency signals during music playback. Advanced ANC takes a new approach, suppressing ambient noise without applying any processing to the music signal.
In-ear microphones listen to the combined signals of music and noise, separating the signal processing of background noise and music. It achieves this by isolating the two from each other in a new, unique algorithm.
The signal collected by the inner microphone analyzes the noise, calculating what should be removed from the playback music signal so that only noise is erased. This means there is no unnecessary processing of the music signal, preserving the purity of the music.
