FAQ for Rechargeable hearing aids

How often should I charge my rechargeable hearing aids?

You should charge your hearing aids every night. The lithium-ion battery can be charged daily, and there is no need to fully discharge the battery before placing your hearing aids back in the charger

How long will the battery last on a full charge?

The daily performance of the battery depends on a number of factors such as the settings in your hearing aids, your hearing loss, the sound environment around you, the age of the battery, and whether you are streaming sound from your phone, TV, or other devices.

Q & As: This Week’s Top Selections

It seems like a lot of hearing aids are now using the ZPower rechargeable battery system. What’s the actual number of hearing aids now using it? Any estimates on how many new hearing aids sold are rechargeable (ZPower and others combined)?
ZPower has had great success in the past 12-18 months. In 2016, we launched a single product, but in 2017, we added an additional 8 hearing aid models that are compatible with the ZPower Rechargeable System. In 2018, we anticipate compatibility with an additional 9 new hearing aid models.

About CMEF

CMEF–Asia Pacific’s medical industry platform serving the entire value chain for the healthcare market, the industry assembly of technology innovation, trading, learning and networking

The China International Medicinal Equipment Fair (CMEF) was launched in the year 1979 and is held twice every year once in spring and the other in autumn, including exhibitions and forums. After 40 years of self-improvement and continuous development, the CMEF has now become one of the world’s leading global integrated service platforms in the value chain of medical devices, covering products and technology, new product launches, procurement and trade, scientific collaboration, academic forums, brand promotion, education and training. The fair widely covers more than ten thousand products, including medical optical and electro-medical devices, smart health-care and wearable equipment, and services including medical imaging, medical examination, in-vitro diagnostics and hospital construction, In recent years, the CMEF has persistently maintained its growth, having innovatively introduced more than 30 subdivided industrial clusters, such as artificial intelligence (AI), computer tomography (CT), magnetic resonance imaging (MRI), operating room, molecular diagnosis, point-of-care testing (POCT), rehabilitation projects, rehabilitation assistive devices and medical ambulances, presenting cutting-edge scientific achievements in the medical industry.

As of now, more than 7,000 medical device manufacturers from over 30 different countries and regions have annually exhibited their products and services with us at the CMEF. For trading and exchanging of medical products and services, about 2,000 specialists and talents and almost 200,000 visitors and buyers including government procurement agencies, hospital buyers and dealers from over 100 countries and regions gather at the CMEF.

Meanwhile, the CMEF has established a series of highly influential sub-brands in the medical field which includes the International Component Manufacturing and Design Show (ICMD), CMEF Congress, CMEF Imaging, CMEF IVD, CMEF Indonesia, CMEF Beijing, the Intelligent Health China and the Beijing International Rehabilitation and Personal Health Show. The establishment of these sub-brands has brought great success to the industry with intelligent medical equipment.

Features of Hearing Aid Technology

Analog versus Digital Hearing Aids

Analog hearing aids have been available for many years.  They have a microphone to collect sound and convert the sound into electrical energy, an amplifier to increase the strength of the electrical energy, and a receiver or speaker to convert the electrical energy to an acoustic sound.  Analog hearing aids may help amplify soft sounds without over-amplifying loud sounds through a process called automatic gain control (AGC).  However, analog hearing aids do not typically have other advanced features.

Digital hearing aids are more complex. With digital hearing aids, a microphone picks up sound, which is then converted into digital signals. The digital signals are then processed by the small computer chip in the hearing aid. Once the digital signal is analyzed and processed using Digital Signal Processing (DSP), it is converted into acoustic sound. DSP allows for changes in volume, but can also provide noise reduction and other features to help improve communication in difficult listening environments.

Currently, very few analog hearing aids are available, and most hearing aids contain DSP. Within digital hearing aids, however, many different features are available and are discussed further in this section.

Gain (volume) Processing

For many years, hearing aids have been able to automatically increase or decrease volume depending on the input sounds. This feature minimizes the need to physically adjust the volume control. However, for most patients with hearing loss, simply increasing or decreasing the volume does not improve the clarity of speech. You may be decreasing sounds that are too loud, but at the same time decreasing sounds that need to be increased to improve speech understanding. You may often notice this with the volume control settings of your television or radio.

More recently, hearing aids are able to separate sound into different frequency (tonal) regions, called channels. The volume of each channel can be adjusted independently, allowing for certain sounds to be amplified more than others, similar to an equalizer on a stereo. The amount of amplification in each channel can generally be adjusted by your audiologist using the hearing aid programming software.

Manual volume controls to change the overall volume are available on many hearing aids. Volume controls may be accessed by a button or volume control wheel on the hearing aid or, in some cases, with remote control.

Number of Frequency Channels

The number of channels available for programming differs among hearing aids. With more channels, hearing aids can be programmed to more accurately fit your hearing loss. Also, with more channels, the analysis of the sound environment is more accurate, which can enhance the function of other hearing aid features. However, more is not always better. More than 15 to 20 channels can cause sounds to become ‘muddy
