Proper use of the hearing aid

Before wearing the hearing aids, be sure to wear the right earmold to the right device and the left earmold to the left device.

It is of utmost importance to verify that the microphone filters are not dirty or clogged, each day should be cleaned with a soft, dry cloth. Never use cleaning products or alcohol for cleaning. Try to have clean and dry hands when having contact with your hearing aids.

When not in use, it is suggested to store the hearing aids in the dehumidifier box, thus protecting them from dirt and possible damage. On the other hand, if you are not going to use the headphones for a long period, it is recommended to remove the batteries.

Hearing aids should not be exposed to a humid environment in order to avoid electronic damage. So, you should remove the headphones when taking a shower, swimming or having contact with water. It is suggested to remove the battery at night so that the battery holder transpires and dehumidifies. Always keep away from pets and small children.

The daily charge level should be reviewed, at the beginning of the day it must meet 100% charge or ensure that the battery functions properly, depending on the case of the hearing device. Regularly, batteries come with an attached label. This label allows batteries to have a longer lifespan. Therefore, it is recommended not to remove this label until the battery is required.

If your hearing device presents any inconvenience, it is advisable to visit the hearing care professional or take him to the experts to avoid irreparable damage.

How to select the hearing aid according to your clinical case?

For the selection of the appropriate hearing aid, the following essential points must be considered:

  • Age
  • Type of Hearing Loss
  • Additional conditions such as Tinnitus
  • Hearing Aid Connectivity
  • Technology type
  • Sound Classes
  • Among others

In order to make the choice of hearing aid as efficient as possible, it is recommended to make an appointment at Audiology Tech Center to receive guidance according to your clinical profile through our specialists. 

Sound

Sound is the perception we have in the brain when receiving mechanical vibrations produced by bodies. These vibrations travel through an elastic, solid, liquid, or gas medium to reach the ear. In a vacuum, sound cannot be produced due to the absence of molecules that can transmit vibrations.

Sound intensity is measured in units called decibels. The safe noise level according to the Environmental Protection Agency (EPA) is 70 decibels. The higher the noise, the less time it takes to cause permanent hearing damage. Below are the noise intervals according to the risk of damage, with their respective examples grounded in everyday life.

 

 

Sound levels of frequent noises

Decibels                                     Source of noise

Safe interval

30                                              Whisper

40                                              Refrigerator

60                                              Normal Conversation

75                                              Dishwasher

 

Risk    range

85                                              Heavy urban traffic, school canteen

95                                              Motorcycle

100                                            Snowmobile

110                        Chainsaw, Drill, Rock Recital, Symphony Orchestra

115                                            Sandblasting

120                                            Ambulance siren, thunder

140-165                                     Firecrackers, firearms

 

According to the Official Mexican Standard NOM-011-STPS-2001, the maximum permissible exposure limits are:

90 dB 8 hours

93 dB 4 hours

96 dB 2 hours

99dB 1 hour

102 dB 30 minutes

105 dB 15 minutes

 

Sound Characteristics

  • Intensity varies according to the amplitude of the sound wave. Allows the difference between high and low sounds. The greater the amplitude, the greater the intensity of the sound.
  • Tone varies with respect to the frequency of the sound wave. At higher frequencies, the sound will be sharp. Conversely, it corresponds to a low sound. Allows the difference between high and low sounds.
  • Timbre varies according to the shape of the sound wave, since each sound source has its own sound characteristics depending on the material from which it is made. It can present the same frequency and intensity at the same time; however, they refer to two different instruments or voices.
