Patent number: 10356535Abstract: A system for capturing an individual's hearing characteristics, including loudness tolerance levels at different sound frequencies, as an individualized shaped auditory profile for automatically enhancing audio to complement and address an individual's hearing deficits experienced via a particular signal pathway including the audio device, the sound environment, and the individual's hearing capabilities. The auditory profile is used to produce enhanced sound subsequently transmitted to the individual via the same signal pathway. The enhanced sound may be produced with consideration of both ears' auditory profile shapes together to increase the dynamic range of the enhanced sound. The sound enhancement can be introduced gradually over a sound reproduction session or a period of time of use.Type: GrantFiled: October 9, 2017Date of Patent: July 16, 2019Assignee: ACE Communications LimitedInventors: Charles Andrew Van Hasselt, Pui Tong Paul Lee, Chi Shan Anna Kam, Ka Kui Cheng

Patent number: 10057683Abstract: A system and method are provided for automatic fitting of all audio signals according to the ear in which a user is using to receive audio signals from a host device. The host device incorporates an audio signal fitting device, which may comprise an inquirer configured to query the host device for an in-use audio producing transducer; an electronic mechanism configured to identify an ear which a user is using to receive audio signals from a host device, based on the in-use audio producing transducer; and a notifier configured to instruct the host device, based on the identified ear, to output a channel of audio signals to the in-use audio producing transducer. The ear in use may be deduced from inertial data.Type: GrantFiled: February 27, 2017Date of Patent: August 21, 2018Assignee: ACE Communications LimitedInventors: Pui Tong Paul Lee, Ka Kui Cheng

Patent number: 9782131Abstract: A system and method are provided for capturing hearing characteristics from self-administered hearing tests, including loudness tolerance levels at different sound frequencies, as an individualized shaped auditory profile for automatically enhancing audio to complement and address an individual's hearing deficits experienced via a particular signal pathway including the audio device used to administer the test, the sound environment, and the user's hearing capabilities. The user may self-administer a hearing test on a smartphone or other device. The shaped auditory profile may be used to produce enhanced sound subsequently transmitted to the individual via the same signal pathway. In some aspects, the invention is useful for any individual seeking an enhanced hearing experience, whether having hearing within normal range or hearing that is impaired.Type: GrantFiled: October 17, 2016Date of Patent: October 10, 2017Assignee: ACE Communications Limited (HK)Inventors: Charles Andrew Van Hasselt, Chi Shan Anna Kam, Pui Tong Paul Lee, Ka Kui Cheng

Patent number: 9138178Abstract: A system and method are provided for capturing hearing characteristics from self-administered hearing tests or from professionally administered hearing tests, including loudness tolerance levels as at different sound frequencies, as an individualized audiological profile for automatically enhancing audio to complement and address as closely as possible an individual's hearing deficits. The user may self-administer a hearing test on a convenient personal apparatus, such as a smartphone. The system includes the ability for capturing an environment profile. The user's hearing is protected against harm in the enhanced audio setting while being provided with the option of a “enhanced hearing” experience. The invention is useful for any individual seeking an enhanced hearing experience, whether having hearing within normal range or hearing that is impaired. Thus the system is useful as a hearing aid.Type: GrantFiled: July 18, 2011Date of Patent: September 22, 2015Assignee: ACE COMMUNICATIONS LIMITEDInventors: Pui Tong Paul Lee, Ka Kui Cheng, Ka Keung John Sung, Ka Cheong Terence Wong, Charles Andrew Van Hasselt, Tan Lee, Chi Shan Anna Kam
