Hearing loss comes in all shapes and sizes. Some people encounter sudden hearing loss associated with a traumatic event while others experience it gradually along with the natural process of aging. Some experience hearing loss in both ears while others experience it in both ears simultaneously. Even those who have hearing loss in both ears may find that it is asymmetrical, affecting one more than the other. These variations in the experience of hearing loss make each case unique. One of the major ways that hearing loss can be categorized is according to the degree of severity. Let’s take a look at some of the ways to understand hearing loss according to that system of categorization.
Diagnosing Hearing Loss
If you’ve recently visited us at Hearing Group for a hearing test, then you are familiar with the process. If you are anticipating your first hearing test, here is a general overview of how hearing loss is diagnosed. Hearing tests come in many forms, but the most common form is pure tone audiometry. In this type of hearing testing, tones are played at different volumes and at different pitches, or frequencies, ranging from low to high. The combination of volume and pitch can result in a sound that you either can or cannot hear. Your hearing specialist would have prompted you to signal by raising your hand or pressing a button each time that you heard a tone.
After this exam, the results are presented in an audiogram. This graph demonstrates the patterns in your hearing. Most people are unable to hear higher frequencies before they lose the ability to hear lower ones, so the chart is used to demonstrate what volume is necessary in order for a person to hear a frequency, from low to high. With this graphic demonstration in hand, an audiologist can determine whether a hearing loss is present and designate the degree of hearing loss experienced.
Degrees of Hearing Loss
The volume at which a sound can be heard is measured in decibels, and each of the degrees of hearing loss designates a range of loudness.
- Mild: The inability to hear sounds under 40 decibels is considered mild hearing loss, but this rage of volume is relatively quiet. Those with mild hearing loss find that they cannot hear sounds as quiet as the rustling of leaves, a whispering voice, or normal breathing. Some have trouble hearing only at high frequencies. Similarly, those with mild hearing loss may be unable to hear voices within a loud environment like a restaurant or concert. This form of hearing loss is also quite commonly not diagnosed. Those who cannot hear these quiet sounds may not even know that they are unable to do so, or they may think it is not a big deal.
- Moderate: Sounds between 40 and 60 decibels register in the range of moderate hearing loss, and these sounds are typical of a quiet office or country home. At this level of hearing loss a person may have trouble keeping up with a conversation at normal volume, even within an otherwise quiet space. Certain sounds, consonants, and accents may be lost in the conversation, leading a person to misunderstand or only partially understand.
- Severe: If you have trouble hearing sounds up to 80 decibels, your hearing loss is considered to be severe. These sounds are relatively loud, such as a vacuum cleaner, hair dryer, or coffee grinder. At this level, a person will almost certainly require assistance in the form of hearing aids in order to be able to get along in public.
- Profound: Those with profound hearing loss are unable to hear sounds until they occur over 80 decibels, such as a lawn mower, food blender, or motorcycle. As you can imagine, aids or other more advanced assistance are required to be able to hear in nearly all situations.
