Many websites talk about hearing loss, they rarely mention how hearing loss changes our hearing in an acoustical and physiological process. The following is a brief summary on how hearing loss affects us. If you want to know more about the details, please check with your audiologist or email me.
Hearing loss affect these areas:

1. Hearing Sensitivity
2. Dynamic Range
3. Frequency Resolution
4. Time Resolution
5. Hearing with Two Ears.

People losing Hearing Sensitivity notice that certain soft sounds are no longer audible with a lot of normal daily sounds become too soft to hear. It affects the overall hearing audibility.
People suffering from a reduced Dynamic Range consider the medium level of sounds as soft sounds and loud sounds which are acceptable by most people may become too loud. For them, their comfortable range becomes a lot smaller than normal hearing.
For people to understand speech, our hearing system must have the ability to identify different pitches of sounds, e.g. “sand” (high pitch ‘s’consonant) and “band” (low pitch ‘b’consonant). Hearing loss can severely damage the ear’s ability to separate different pitches of sounds which makes it difficult for people to identify words in conversation. The Frequency Resolution problem can cause hearing difficulty in all situations.
Speech consists of many different elements in various speeds, for instance strong vowels alternating with soft consonants. Hearing loss reduces the hearing system’s ability to separate the two sounds from each other (Time Resolution). With poor Time Resolution in your hearing system, your speech understanding in background noise situations become difficult.
The brain constantly compares sounds received from the two ears (Binaural Auditory Processing). This help us to locate the sounds and the movement of the sounds. The comparison process also helps suppress unwanted sounds. Hearing loss can affect sound localization and reduce our speech understanding in noisy environments.
Hearing loss is not as simple as many people think. Audiologists are professionals trained to help people understand their hearing problems and suggest hearing solutions.
