A system includes a first scanner comprising an inflatable membrane configured to be inflated with a medium to conform an exterior surface of the inflatable membrane to an interior shape of a cavity, the medium attenuating, at a first rate per unit length, light having a first optical wavelength, and at a second rate per unit length, light having a second optical wavelength. The system comprises an emitter and detector configured to generate and receive light from the interior surface of the inflatable membrane, respectively. A processor is configured to generate a first electronic representation of the interior shape and a second electronic representation of a second shape based on the received light. A design computer is configured to combine the first and second electronic representation into a combined electronic representation corresponding to at least a portion of the interior shape based on at least one or more native references.

Systems and methods for using native references in custom object design

Methods of operating an audio device are provided. A method includes measuring sound pressure levels (SPL) for acoustic energy received by an ear canal microphone (ECM) during a time increment &#x394;t and calculating a SPL_Doseduring the time increment &#x394;t using SPL.

Earhealth monitoring system and method II

The technology described in this document can be embodied in a method that includes receiving one or more electronic files comprising information on structural features of a portion of an ear of a user, generating an electronic representation of the eartip or a cast based on a portion of the information on the structural features of the portion of the ear, and producing the eartip based on the electronic representation. The eartip includes an outlet, and a sealing structure disposed around an exterior of the outlet, wherein a first end of the sealing structure is attached to the outlet, and a second, opposite end of the sealing structure is physically separated from the exterior of the outlet. Generating the electronic representation includes configuring one or more structural parameters of the outlet or the sealing structure in accordance with the structural features of the portion of the ear.

Customized ear tips

A system includes a first scanner having an inflatable membrane configured to be inflated with a medium to conform an exterior surface of the inflatable membrane to an interior shape of a cavity. The medium attenuates, at first rate per unit length, light having a first optical wavelength, and attenuates, at a second rate per unit length, light having a second optical wavelength. An emitter is configured to generate light to illuminate the interior surface and a detector is configured to receive light from the interior surface. The scanner further includes a processor configured to generate a first electronic representation of the interior shape based on the light. A design computer is configured to modify the first electronic representation into a three-dimensional shape corresponding to at least a portion of the interior shape and a fabricator configured to fabricate, based at least on the modified first electronic representation, an earbud.

Methods of operating an audio device are provided. A method includes measuring sound pressure levels (SPL) for acoustic energy received by an ear canal microphone (ECM) during a time increment &#x394;t; and calculating a SPL_Doseduring the time increment &#x394;t using SPL.

A system for monitoring sound pressure levels at the ear includes an ambient sound microphone (ASM) for receiving ambient sounds and an ear canal microphone (ECM) for producing audio signals as a function of ambient sound received at the ambient sound microphone and a sound signal received from an associated personal audio device. A logic circuit is operatively associated with the ASM and ECM calculates a total SPL_Dose experienced by the ear at a time t. The total SPL_Dose is calculated by determining SPL_Dose for periods &#x394;t as measured at the ECM. The logic circuit may select an action parameter in response to the Total SPL_Dose.

Earhealth monitoring system and method IV

Systems and methods for monitoring a sound pressure level dose at an ear are provided. A system includes an audio transducer which outputs a sound signal is placed within an ear to receive sound at the ear. A sound level threshold detector determines whether a sound pressure level of the sound signal is at a minimum level and outputs a sound pressure level signal corresponding to the sound pressure level when the sound pressure level is not at the minimum level. A time period is calculated during which the sound pressure level is not at the minimum threshold level. A listening fatigue calculator determines whether a cumulative effect of exposure to the sound signal at the ear over the time period will cause harm to the ear. At least a portion of the system is disposed in situ at the ear.

Methods of operating an audio device are provided. A method includes calculating estimated sound pressure levels (SPLs) for drive signals directed to an ear canal receiver (ECR) during a time increment &#x394;t; calculating an estimated SPL_Dose during the time increment &#x394;t using the estimated sound pressure levels; and calculating a total SPL_Dose at a time t of the audio device using the estimated SPL_Dose.
