Description

Technical Field

[0001] This invention relates to the field of hearing aid testing technology, and in particular to a hearing aid battery life testing system and method. Background Technology

[0002] With the aging population and the increasing number of people with hearing impairments, hearing aids, as an important hearing assistive device, have attracted much attention regarding their performance and quality. Battery life is one of the key performance indicators of hearing aids, directly affecting the user experience and the practicality of the device.

[0003] Traditional methods for testing hearing aid battery life have several shortcomings. Firstly, the testing process lacks systematicity and standardization. Different testing institutions or manufacturers may employ different testing procedures and standards, leading to a lack of comparability in the results. For example, some tests are conducted only in a single operating mode, while hearing aids switch between multiple modes in actual use, making such tests unreliable in reflecting their true battery life performance. Secondly, existing testing methods largely rely on manual operation, which is inefficient and prone to human error. During the testing process, frequent data recording and equipment monitoring by personnel are required, and prolonged testing can easily lead to operator fatigue, thus affecting the accuracy of the results.

[0004] Furthermore, for some newer hearing aids, such as those with smart features and Bluetooth connectivity, their power consumption characteristics are more complex, making it difficult for traditional testing methods to comprehensively and accurately assess their battery life. Because the activation of these functions dynamically changes the hearing aid's power consumption, existing testing methods cannot simulate the power consumption when multiple functions are used alternately in real-world scenarios, leading to significant discrepancies between test results and actual usage. In conclusion, developing a systematic, efficient, and accurate hearing aid battery life testing system and method is of significant practical importance. Summary of the Invention

[0021] A hearing aid battery life testing system includes a power simulation module for simulating batteries of different types and capacities to provide a stable power supply to the hearing aid under test, with its output voltage... Through formula The calculation module simulates various working modes of a hearing aid in actual use and automatically switches them according to a preset time sequence.

Different variation curves are used to accurately simulate battery discharge characteristics.

[0023] The working mode simulation module includes quiet environment mode, noisy environment mode, Bluetooth connection mode, multi-person dialogue environment mode, and sports environment mode. The parameter settings for each mode are set according to the working state of the hearing aid in the actual use scenario. For example, the amplification is higher in noisy environment mode than in quiet environment mode, and Bluetooth-related circuits are enabled in Bluetooth connection mode.

[0024] The power consumption monitoring module uses high-precision current and voltage sensors. The accuracy of the current sensor reaches ±0.1mA, and the accuracy of the voltage sensor reaches ±0.01V, to ensure that the collected current and voltage data are accurate and reliable, thereby ensuring the accuracy of the calculated power consumption data.

[0028] The system also has data storage capabilities, storing all data from the testing process, including power consumption data, working mode switching time, and battery life calculation results, in a database for subsequent querying and analysis, providing data support for product quality traceability and performance comparison.

[0029] The testing method for a hearing aid battery life testing system includes the following steps: Initialize, set the power simulation module parameters to simulate the required battery type and capacity, and set the working mode sequence and switching time of the simulation module. The test begins, the power simulation module is activated to power the hearing aid, the working mode simulation module switches working modes according to a preset sequence, and the power consumption monitoring module monitors power consumption data in real time and transmits it to the data processing module. Data processing: The data processing module calculates the average power consumption and battery life under different working modes, and performs data analysis and statistics. Generate a report based on the data processing results, including detailed test reports such as battery life and power consumption curves under different working modes.

[0030] During the initialization process, various system parameters also need to be calibrated, including the sensor calibration of the power consumption monitoring module, to ensure the accuracy of the detection data. The calibration process involves comparing the sensor output parameters with a standard power source. Example

[0031] Testing a traditional analog hearing aid: First, the power simulation module was set to simulate a common zinc-air battery. Based on the discharge characteristics of zinc-air batteries, the initial output voltage was set to 1.4V. As the test process simulated battery discharge, the output voltage was gradually reduced. The operating mode simulation module was set to two operating modes: quiet environment mode and noisy environment mode, automatically switching every 30 minutes. In quiet environment mode, the power consumption monitoring module detected that the hearing aid's current consumption was stable at around 1.5mA, and the voltage was 1.3V. According to the formula P=VI, the power consumption at this time was calculated to be P1=1.3V×1.5mA=1.95mW. In noisy environment mode, due to the increased amplification of the hearing aid, the current consumption rose to 2.5mA, while the voltage remained at 1.3V. At this time, the power consumption was P2=1.3V×2.5mA=3.25mW. Based on the power supplied by the power simulation module and the power consumption in different modes, the data processing module calculated that under this simulated usage condition, the battery life of this traditional analog hearing aid was approximately 20 hours.

[0032] Generating a test report: The data processing module plots the power consumption data during the test as a curve, with time on the horizontal axis and power consumption on the vertical axis. The report also details the average power consumption in quiet and noisy environments, the duration of each mode, and the total battery life, providing manufacturers with comprehensive data support for product improvement. Example

[0033] Testing the digital programmable hearing aid: The power supply simulation module simulates lithium battery power, with an initial voltage set to 3.7V. The operating mode simulation module is set to quiet environment mode, noisy environment mode, and Bluetooth connection mode, switching between them every hour. In quiet environment mode, the power consumption is P3=1.8mW; in noisy environment mode, the power consumption is P4=3.5mW; when Bluetooth connection mode is enabled, the current consumption increases significantly, reaching P5=5mW. The power consumption monitoring module records these data in real time and transmits them to the data processing module.

[0034] Analysis of test results: The data processing module analyzes the results according to the formula. After calculating the battery life and taking into account the weighting of usage time in different modes, the final battery life of this digitally programmable hearing aid under comprehensive usage scenarios was determined to be 15 hours. Based on this test result, the manufacturer optimized the Bluetooth connection circuitry, reducing power consumption during Bluetooth connection, and after further testing, the battery life was increased to 18 hours. Example

[0035] The intelligent adaptive hearing aid is tested as follows: The power simulation module mimics an alkaline battery, with the output voltage gradually decreasing from 1.5V. The operating mode simulation module simulates various complex scenarios, including quiet environments, noisy environments, multi-person conversation environments, and sports environments. The duration of each environment is set according to the actual usage probability. In a quiet environment, the hearing aid automatically adjusts the amplification factor through an intelligent algorithm, with power consumption of P6=1.6mW; in a noisy environment, to ensure speech clarity, power consumption increases to P7=4mW; in a multi-person conversation environment, due to the need to process multiple sound sources simultaneously, power consumption reaches P8=4.5mW; in a sports environment, considering the impact of body movement on the microphone and possible Bluetooth connection requirements, power consumption is P9=5.5mW.

[0036] Optimized testing scheme: During the testing process, the control module dynamically adjusts the duration and switching sequence of each mode based on feedback from the data processing module to more accurately simulate real-world usage. Through multiple optimizations of the testing scheme, the final battery life of the intelligent adaptive hearing aid in real-world usage scenarios was determined to be 12 hours. This test result provided direction for further product optimization. The manufacturer improved the intelligent algorithm, reducing power consumption in complex environments, thus increasing the product's battery life to 14 hours.
