Have you had difficulty finding a quiet place to relax, or a restaurant to enjoy a good meal with friends without too much noise from the background? Sometimes the noise level of a venue can get too loud that a pleasant conversation is impossible. Here’s a mobile app that we have come across, during the ASA meeting in New Orleans held earlier this month, called SoundPrint that helps users locate quiet venues on map. Users can search keywords (Figure 1) or look directly on the map, venues are displayed with their decibel levels (Figure 2). The app categorises venues into quiet, moderate, loud and very loud areas, so users can easily find quiet or vibrant venues according to their preference. With the app, users can also measure the loudness of a venue in decibels (Figure 3), which contributes to the database of the app, and enables users to determine whether a venue is too loud or not (>80dB), to reflect to the manager for improvement.
Sometimes it is hard to find quiet places nearby when you want to escape from the hustle and bustle of the city. We came across a mobile app that helps users find quiet areas close by to relax. Hush City, an app introduced during the ASA meeting in Boston earlier this year, helps users find these “everyday quiet areas” on a map of quietness (Figure 1). The app also encourages users to explore quiet spots in their neighbourhoods by allowing them to record sounds and measure sound levels in decibels with the app (Figure 2). Users can answer a questionnaire of feedback on the sound spot (Figure 3). The collected data and feedback are used for the map of quietness. This actively engages the public in sonic environment evaluation and planning.
A melting pot of Eastern and Western characteristics, Hong Kong is thronged with restaurants gratifying your palate with a diversity of flavours. The unlimited variety of food in every class has given Hong Kong the reputable labels of “Gourmet Paradise” and “World’s Fair of Food”. With Chinese being the most predominant cultural group in Hong Kong, Chinese food forms the backbone of dine-out scenes. Chinese restaurants in Hong Kong are adored by locals and tourists alike.
Everyone having been to a Chinese restaurant must have noted how loud and noisy the place can be. Yum Cha is usually a happy and boisterous occasion, when family and friends gather to sip tea and eat dim sum. It has been measured that the noise level at various Chinese Restaurants ranged from 66.4 to 79.7 dB(A). It is the mingled sound of eating utensils colliding, food being chewed and devoured, diners’ hearty laughs and animated chatting, and announcement of dishes being served. Although it is hardly gentle to the ears, people usually stay long in a Chinese restaurant. Being noisy accords with most people’s conceptions or expectations of Chinese restaurants and diners usually get used to the volume after some time.
Imagine the restaurant noise is much cut down, how do you think the Chinese dining experience will be altered?
