VHH and FHH are two different types of hearing assistance devices. VHH, or Variable Hearing Help, is a hearing aid that is worn behind the ear and adjustable for different levels of hearing impairment. This type of device is more versatile and can be customized to fit a person's particular needs. On the other hand, FHH or Frequency Help Hearing is a specialized hearing aid that works through the use of multiple frequencies to enable its user to hear better. FHH is designed to provide a wide frequency range which can be adjusted to fit the user needs.
Both VHH and FHH have their advantages and disadvantages. VHH is more customizable and can have multiple frequency settings, while FHH is designed to provide a wider frequency range for a specific user. However, VHH also comes at a much higher cost than FHH, as it requires fine tuning and customization. Additionally, FHH requires professional help in order to determine the best settings for the user.
Overall, both VHH and FHH can provide great hearing assistance, however it is important to consider the cost and features when choosing the best hearing aid for your individual needs.
