Notification sounds are audio alerts that signal the arrival of new messages, updates, or reminders on electronic devices. These sounds can be customized for different applications, such as email, text messages, or social media, allowing users to identify the source of the notification without looking at their device. Typically, notification sounds are short and distinct, designed to grab the user's attention without being overly disruptive. Many devices, including smartphones, tablets, and computers, come with a variety of pre-installed sounds, and users can often choose or create their own to personalize their experience.
