What’s Your Hearing Number?

Welcome to our latest blog post! Today, we’re delving into an often-overlooked aspect of our health – the ‘hearing number’. Much like knowing your blood pressure or cholesterol levels, understanding your hearing number is crucial for maintaining good health. But what exactly is a hearing number, and why is it important? Let’s explore.

What Does ‘Hearing Number’ Mean?

A hearing number is a succinct yet comprehensive measure of your hearing health, obtained through a hearing test conducted by an audiologist. It primarily indicates the quietest sounds you can hear across various frequencies, offering a detailed insight into your auditory sensitivity. During the test, you’re exposed to sounds of different pitches and volumes, and your response to each sound is recorded. This data is then plotted on an audiogram – a visual representation of your hearing abilities across the sound spectrum.

But the hearing number encompasses more than just your ability to detect soft sounds. It also includes aspects such as your ability to understand speech in different environments, discern between different sounds, and how well you can follow conversations in noisy settings.

How Is a Hearing Number Determined?

Determining your hearing number involves a comprehensive hearing test, which assesses:

  • Threshold of Hearing: The softest sounds you can hear at different frequencies.
  • Speech Understanding: How well you understand speech, especially in noisy environments.
  • Tympanometry: Examining the health of your middle ear.

Why Is Knowing Your Hearing Number Important?

  • Early Detection of Hearing Loss: Just like regular health check-ups, knowing your hearing number can help in early detection of hearing loss, which is crucial for effective management and treatment.
  • Personalised Hearing Care: Your hearing number helps audiologists to create a tailored approach for any required hearing interventions, ensuring you receive the most effective care.
  • Awareness and Prevention: Understanding your hearing number can motivate you to take preventive measures against hearing loss, such as avoiding prolonged exposure to loud noises.

Interpreting Your Hearing Number

Your hearing number, crucial for understanding your hearing health, is typically represented by an audiogram. This graph illustrates the softest sounds you can hear at different frequencies, measured in decibels (dB). The audiogram visually plots your hearing thresholds across a spectrum of pitches, offering a detailed view of your hearing sensitivity.

Normal hearing typically ranges between -10 to 20 dB, indicating the ability to hear soft to loud sounds comfortably. A hearing number within this range suggests normal hearing. On the other hand, a hearing number outside this range, especially above 20 dB, may signal hearing loss. The severity of hearing loss is gauged by how much your thresholds exceed this normal range on the audiogram, with higher dB thresholds indicating greater degrees of loss.

Additionally, the audiogram can identify specific types of hearing loss, like difficulty in hearing high-frequency sounds. This detailed insight is critical for customising hearing aids or other interventions for your specific hearing profile.

In essence, the audiogram and your hearing number offer a clear, measurable understanding of your hearing ability, guiding you and your audiologist in managing your hearing health effectively.

Lifestyle and Your Hearing Number

Your hearing number can vary over time, influenced by aging, noise exposure, and overall health. As we age, natural changes in our ears can affect our hearing, a process known as presbycusis. Similarly, frequent exposure to loud noises, whether from work environments, entertainment, or daily life, can lead to noise-induced hearing loss. Maintaining a healthy lifestyle, including managing chronic conditions and avoiding ototoxic medications, can also impact your hearing health.

Regular hearing check-ups are crucial for tracking these changes. They allow for early identification of any hearing loss and adjustments to your hearing care plan. Staying proactive and adapting to these changes can help preserve your hearing quality, enabling you to enjoy the sounds of life fully.
